This is not an ad – we focus on reliable, educational content backed by user feedback and professional reviews. Thanks to this, you’ll be able to decide which MOZA base is the best fit for you.

MOZA R3 Bundle – the smallest 3.9 Nm base for beginners

Characteristic

MOZA R3 is the newest and smallest wheelbase in the lineup – delivering a peak torque of 3.9 Nm. It was designed as an affordable entry into the world of direct drive for users coming from simpler wheels like Logitech or Thrustmaster. Despite its seemingly low 3.9 Nm, the R3 offers much smoother and more precise force feedback than popular gear-driven models – users emphasize that switching from a Logitech G29 to the R3 is a huge improvement (though over time, you may find yourself wanting even more torque). R3 base uses a direct drive system and a 72 W servo motor, which translates into realistic and stable FFB effects.

For whom?

Model R3 is ideal for beginner simracers who want to try direct drive but don’t need high torque right away. It’s also a great option if you’re limited by budget or space – R3 is smaller and lighter than the other wheelbases, and its maximum torque is safe for learning (lower risk of injury or fatigue during long sessions). It's also the only MOZA base officially supporting consoles: R3 is available in an Xbox-dedicated bundle (licensed for Xbox One/Series) as well as in a version for PC . If Xbox compatibility is important to you, R3 is currently the only choice – MOZA aimed to make the R3 its first console product (the Xbox bundle launch was slightly delayed due to licensing issues).

Sets and accessories

On Simline you'll find the MOZA R3 Bundle PC and R3 Bundle Xbox/PC – ready-to-race kits featuring the R3 base. They include the MOZA ES steering wheel, two-pedal SR-P Lite set, and a dedicated desk clamp. This bundle allows you to get started right away – the ES Steering Wheel is a simple D-shape rim with a universal layout, but there are mods available like the MOZA ES Formula or 12-inch Round Wheel Mod . The SR-P Lite pedals come with throttle and brake, with an optional clutch pedal available separately . However, we recommend the Brake Performance Kit for better pedal differentiation – it significantly improves trailbraking and muscle memory during braking. Mounting the R3 base is very easy – the included table clamp fits desks up to 5 cm thick. The base itself is compact and lightweight, ideal for use on a desk or a folding stand . Importantly, the R3 is quiet – with 3.9 Nm it doesn’t require active cooling (no noisy fan), and its smart thermal management protects the motor from overheating.

Driving impressions

MOZA R3 offers incomparably better feedback than any gear-driven wheel – even at the same nominal torque. Users describe the transition from a Logitech G29 to the R3 as “like going from a toy to a real simulator.” The force feedback is smooth and detailed – you’ll feel the road texture, catch the loss of grip, and suspension response far more clearly than on previous-gen consumer gear. Of course, 3.9 Nm is still on the lower end compared to higher-end DD models, so the strongest effects (e.g., rally or drift) will be more subtle. On the flip side, beginners will appreciate that the R3 doesn’t yank the wheel too hard, making it easier to handle at first.

Summary

If you're just starting out or mostly race for fun in less demanding simulators (like ETS2, Forza, or arcade games), the MOZA R3 is a great choice. You get direct drive technology in an accessible format and price point, plus the ability to play on console. Just keep in mind that “appetite grows with experience” – many players eventually crave stronger FFB. Luckily, MOZA’s ecosystem makes it easy to upgrade later ( wheel rims and accessories are compatible across bases ). R3 is a solid entry-level base to get serious about simracing.

MOZA R5 – 5.5 Nm for ambitious drivers (budget Direct Drive)

Characteristic

MOZA R5 is a 5.5 Nm wheelbase – a classic entry-level direct drive system competing with the likes of Fanatec CSL DD (5 Nm) and Logitech DD Pro. With 5.5 Nm of torque, it delivers much stronger and richer FFB effects than any Logitech wheel – reviewers consistently point out that R5 offers a level of detail simply unreachable for gear or belt-driven systems. In practice, this means you’ll feel every curb, subtle front-end lift-off during braking, or rear-end slip in a drift – sensations you won’t get on lower-end devices. Users switching from Logitech G29/G923 to MOZA R5 describe the difference as “night and day” – praising the sturdy construction of the base and wheel, the lack of play, and the absence of the “soft” feel found in belt-driven systems. The R5 is built entirely from aviation-grade aluminum, ensuring high durability and no unwanted vibrations from the housing.

There are two bundle variants based on the R5 base: MOZA R5 Bundle and MOZA R5 Truck Bundle

For whom?

MOZA R5 is aimed at beginner and intermediate simracers who want to take the hobby seriously but are working with a limited budget. It’s the perfect first direct drive – relatively affordable yet powerful enough to deliver a realistic racing sim experience. With 5.5 Nm of torque, it can realistically replicate forces in GT cars, open-wheelers, or R2/R3 rally cars. The R5 is also a good option if you’re using a desk – it remains compact (much smaller than the R16/R21) and comes bundled with a table clamp. On the other hand, if you’re already experienced with FFB and feel that 5 Nm isn’t enough, you might want to look at a stronger base like the MOZA R9 . Still, many players say that the R5 hits the “sweet spot” – offering most of the direct drive advantages with a reasonable torque and price point.

Kits and assembly

MOZA R5 is most often purchased as a complete package – the R5 Bundle (PC) includes the base, MOZA ES steering wheel, and SR-P Lite pedals. This bundle is often recommended as the best entry into simracing in the ~€450 price range. It also includes a table clamp (different from the R9/R12 version – simpler, but functional). Note that the MOZA R5 does not have an official console version – it's a PC-only device, but with the MOZA ESX wheel and mods, you can convert it into a formula-style version or a 12-inch round wheel mod. Desk mounting is possible and relatively stable, although at the full 5.5 Nm output it's best to use a sturdy desk (up to 50 mm thick, as recommended by MOZA). The R5 base features efficient passive cooling (smart cooling system keeps the temperature in check). For better brake pedal feel, we recommend the Brake Performance Kit to improve brake modulation.

Driving impressions

MOZA R5 from the starter bundle instantly gives a taste of professional simracing. The included ES steering wheel has a diameter of approx. 280 mm, which combined with the 5.5 Nm base gives a feeling close to driving a real sports car. The force feedback is surprisingly strong for such a small device – many users drive their first laps at reduced power, as the full 5.5 Nm can already give a solid “kick” on curbs or during slides. Additionally, the FFB detail level is impressive (thanks to the high-resolution sensor – 15-bit encoder with 32,768 ppr). Even small bumps or grip changes are clearly noticeable. Reviews highlight that the R5 delivers very smooth steering feel – there's no “grinding” or dead zone like in cheaper wheels. This makes it easier to feel the car’s balance, which translates into better lap times and a more immersive experience.

Summary

Since MOZA R5 is the entry-level DD model, MOZA made sure it can be upgraded over time. The most important improvement is upgrading the pedals: the R5 base supports (via USB) MOZA SR-P pedals with a 100 kg load cell on the brake. This upgrade offers a huge improvement in brake precision compared to the stock SR-P Lite pedals (which use only springs and elastomer). MOZA has also introduced CRP2 pedals – a higher-end set with full metal construction, load cell, and adjustability – and even the innovative mBooster active pedals – showing the expansion of the MOZA ecosystem. As for steering wheels, the R5 is fully compatible with all current MOZA wheels – all working wirelessly. In daily use, the R5 is practically trouble-free – the only drawback might be that your appetite for more grows, and after a year you may want more power. When that time comes, you’ll find MOZA R9 waiting for you ?.

MOZA R9 (V2 / V3) – 9Nm for mid-level enthusiasts

Characteristic

MOZA R9 is the most popular base from MOZA – with 9 Nm of torque, it's a universal choice for advanced amateurs and semi-professionals. It delivers twice the power of the MOZA R5 , resulting in much stronger and richer FFB effects. 9 Nm is enough to replicate the full steering force range of most race cars (for comparison – professional F1 simulators typically use 12–15 Nm). MOZA R9 is known for its compact design: the entire case is made of aviation-grade aluminum, yet the overall size remains small for this power class. Inside is an advanced servo motor with passive cooling – the R9 base features a solid aluminum housing that efficiently dissipates heat. Importantly, the R9 was designed from the ground up for minimal latency and high resolution – it features a 15-bit encoder (32768 ppr), and its electronics refresh input signals at 1000 Hz. In practice, this means ultra-smooth operation and zero perceptible delay between the simulator and your steering movements.

Versions V1 vs V2 vs V3

MOZA R9 base has gone through minor updates. The R9 V1 (first version) communicated with the steering wheel only wirelessly, which turned out to be a limitation – for example, it wasn’t compatible with the budget MOZA ES wheel, which requires a wired connection. In the R9 V2 version, a wired connection in the quick-release was added (along with appropriate pins in the hub), solving the issue – R9 V2 supports both wireless and wired rims (like the ES ). In addition, R9 V2 received a slightly updated rear panel with extra ports (including connections for MOZA pedals and handbrake). In early 2025, MOZA released the R9 V3 version, featuring an upgraded encoder with 21-bit resolution. In their marketing, MOZA R9 V3 still promotes “wireless power and communication” for the wheel and smart temperature control. In other words, R9 V3 combines the best of V1 (wireless convenience) and V2 (wired stability) with some small improvements. For the buyer, it’s important to know that every R9 version offers roughly the same power and driving experience – if you find a deal on the R9 V2 , grab it – the differences from V3 are minimal in day-to-day use.

For whom?

MOZA R9 is a great option for demanding enthusiasts. If 5 Nm from the CSL DD or R5 isn't enough for you, 9 Nm will take your realism to the next level. This base can really snap the wheel when hitting curbs or during aggressive drifting — in untrained hands, it might even sting a little, which just shows its potential. R9 is appreciated by sim racers who enjoy varied disciplines: from GT3 and circuit racing, through rally and drift, to Formula 1. In all of these use cases, 9 Nm performs at least very well. For example, drifting a BMW E30 in Assetto Corsa delivers fast countersteering with serious strength, while in F1 2022 you will clearly feel the rising resistance at high speeds. What’s important is that R9 still sits somewhere between consumer and professional gear – it already requires a more robust setup than a regular desk, but it won’t destroy your rig. It can be mounted on a strong desk or stand, though a cockpit is recommended for maximum stability. MOZA offers an optional table clamp for R9 so desk mounting is possible – just make sure nothing wobbles when running full 9 Nm.

Kits and wheels

Simline offers the R9 V2 and R9 V3 bases both as standalone units and in bundles with various steering wheels: including options like R9 + KS wheel (GT-style, butterfly shape, 300 mm), R9 + CS V2P (330 mm round mid-range wheel), R9 + RS V2 (advanced round wheel with LED display), or R9 + FSR Formula (full-spec F1 wheel with screen). This makes it easy to tailor your bundle to your driving style: for drift and rally fans, the bundle with a large round wheel (CS or RS) provides a firm grip and wide rotation angle; for GT3 lovers – the bundle with the MOZA KS (GT-style, flat bottom, ergonomic button layout); and for F1 enthusiasts – the FSR2 bundle with butterfly shape and dual-clutch paddles. Of course, steering wheels can also be purchased separately – the R9 base is compatible with all new-gen MOZA rims (V2), both wirelessly and via cable. For example, MOZA GS V2 (12 buttons, carbon paddles) or MOZA FSR2 will work plug & play without adapters. It’s worth noting that older MOZA V1 wheels (like GS V1) are still compatible with R9 V2/V3 – MOZA has maintained backward compatibility, with the exception of the budget ES rim which required a V2+ base. There are also more premium options like the MOZA Vision GS or the licensed gem – MOZA Lamborghini Squadra Corse Essenza SCV12 .

Driving impressions and opinions

MOZA R9 receives highly positive reviews in the simracing community. Many drivers consider it the “sweet spot” – a wheelbase that delivers high-end sensations at a moderate price. When compared to the Fanatec CSL DD 8 Nm, it often performs equally well, or even better (thanks to the extra 1 Nm of torque). Tests show that the R9 uses a different cooling strategy – it doesn’t have large external heat sinks, instead relying on passive cooling. In practice, you won’t notice a difference under normal use, apart from the R9 being slightly warmer to the touch after a long session. Noise is minimal. In terms of precision, the R9 rivals more expensive bases: there's no perceptible delay, and its 21-bit encoder ensures smooth, accurate response. The force feedback is described as “strong and very detailed”. Users and reviewers particularly praise the MOZA FFB filtering algorithms – the R9 base features a quad-core CPU architecture, ensuring even complex effects are processed without lag. For example, in iRacing, you can feel both engine vibrations at idle and harsh impacts when hitting a wall. Additionally, all MOZA wheelbases support 360Hz FFB refresh rate in iRacing.

One quote from the forums sums it up well: “Moza R9 feels like a DD1 with a limiter – I never feel like I’m missing anything during normal driving.” Of course, the DD1 (20 Nm) has much more headroom, but most drivers won’t push past ~9 Nm anyway to avoid fatigue. That’s why the R9 is often regarded as the best mid-range option. The only caution mentioned is the ecosystem pricing – MOZA wheels can be pricey, pushing up the total setup cost (a top-tier wheel can cost as much as the base). Fortunately, there are more affordable alternatives like ES or CSv2p . In summary, MOZA R9 V2/V3 is an excellent base for serious simracing. If you already have a sturdy cockpit and want to experience the full potential of direct drive without spending a fortune on high-end gear, the R9 will deliver.

MOZA R12 (V1 vs V2) – 12 Nm semi-professional and future-proof

Characteristic

MOZA R12 v2 is a wheelbase offering a peak torque of 12 Nm, placing it between the R9 v3 and the R16 v2 – serving as a bridge between enthusiast and professional-grade equipment. 12 Nm is a level of force that only a few years ago was reserved for high-end devices like the Fanatec Podium or Simucube 2. Here, you get this power in a relatively compact case at a much more accessible price. R12 v2 features the next generation of Force Feedback algorithms (NexGen 3.0), which translates into extremely detailed and responsive feedback in practice. The base’s outer shell is similar in design to the MOZA R9 v3 . However, underneath that stylish exterior lies an engineering upgrade focused on performance: R12 includes a more powerful power supply, more efficient cooling system, and higher precision in operation compared to the R9 .

R12 V1 vs V2 – differences

MOZA R12 v2 is the current version of this base – but how does it differ from the MOZA R12 V1 ?

The only change is the encoder – the current version uses a high-grade 21-bit encoder. All MOZA bases now support 360Hz FFB refresh rate in iRacing.

For whom?

MOZA R12 v2 is aimed at advanced simracers and semi-professional applications. 12 Nm is a torque level that will satisfy the vast majority of users – it’s sufficient even for simulating cars without power steering (classic Formula cars, vintage race cars), and at the same time not as extreme as 16–21 Nm, so you can still use its full strength without worrying about safety. R12 is often chosen by users who frequently race in endurance events, GT3, LMP, and rally. In GT cars, 12 Nm allows you to feel every detail – where the R9 might have lacked punch when hitting high curbs, here you’ll feel it clearly. In rally cars, the 12 Nm delivers strong jolts over stones or jumps, enhancing realism in Dirt Rally or RBR. Despite its high power, R12 is still manageable even on a desk setup – officially MOZA allows mounting the R12 to a desk using the same clamp as the R9 . However, you need a truly sturdy, rigid desk and proper tightening, because 12 Nm can move lighter setups. A solid cockpit is strongly recommended – R12 has standard mounting holes on the base and four front-facing mounting holes as well. If you're thinking about the future (e.g., console support), it's worth noting that R12 V2 is console-ready – MOZA announced Xbox compatibility when paired with the licensed MOZA ESX wheel .

Sets and accessories

Simline offers R12 bundles with various steering wheels, just like with the R9. For example: MOZA R12 + KS (versatile GT set), MOZA R12 V2 + CS V2P (for classic round wheel lovers), MOZA R12 V2 + RS V2 (for high-end users), or the impressive MOZA R12 + FSR Formula Bundle (with a top-tier racing wheel). R12 pairs excellently with MOZA’s professional wheels, such as MOZA GS V2 (GT) or MOZA FSR (F1) – both take full advantage of the base’s power and offer plenty of buttons, clutch paddles, LED displays, and more. For the R12 base, it is recommended to choose load cell pedals – at minimum MOZA SR-P (100 kg sensor) or preferably the new MOZA CRP2 to ensure braking precision matches steering control. It’s also worth considering accessories such as the MOZA HBP handbrake (if you enjoy rally/drift) or the SGP sequential shifter – R12 V2 has dedicated ports, so accessories like the shifter and handbrake can be plugged directly into the base – keeping cables tidy and freeing up USB ports on your PC.

Driving impressions

Users switching to 12 Nm are often surprised by how much power reserve they now have. Many set the force to around 70–80% and leave headroom for the heaviest moments (e.g. impacts). Thanks to the high torque, force feedback doesn’t clip – even during sudden events on track, the base doesn’t max out and flatten the signal, which can happen with weaker models. MOZA R12 also stands out with its excellent smoothness and response. The new FFB filtering system ensures that effects are strong yet free from jolts or artifacts. For example, center forces at high speed are noticeable but don’t cause uncomfortable vibrations – MOZA implemented a Speed-dependent Damping feature that enhances stability during fast driving. MOZA R12 is also very smooth – thanks to optimized motor design, there’s no “notching” or resistance when rotating the wheel slowly. This is thanks to the rotor design and high resolution – 12 Nm models feature 21-bit encoders, ensuring great precision.

In terms of noise levels, MOZA R12 is no louder than the MOZA R9 – it may become warm or even hot after long sessions, especially in summer. However, the smart cooling system is highly effective – the base maintains stable performance even during hours-long endurance races, with no throttling or drop in strength. The case itself acts as a heatsink, and thermal management algorithms monitor temperature in real time. Users praise the R12 for its reliability and consistency – crucial for users who train regularly or participate in long league sessions. A practical safety feature is the built-in Hands-off Protection mode – the base detects when you let go of the wheel and immediately halts potential oscillations, preventing uncontrolled spinning. This significantly improves safety with strong FFB.

Summary

MOZA R12 V2 is an excellent choice for those who want more than 8–9 Nm, but don’t necessarily need 16 or 21 Nm right away. It delivers professional-grade force feedback, making it suitable for e-sports competition (many simracing leagues use ~12 Nm bases as the standard), without the high-end price tag. If you're planning a long-term journey into simracing, R12 is a smart investment – it offers future-proof power, full compatibility with MOZA accessories, and console support (making it more versatile). Compared to the MOZA R16 V2 you'll get a very similar experience for a bit less money – the 4 Nm difference will be noticeable mostly to the most dedicated FFB enthusiasts. For most users, 12 Nm is already “more than enough”, as confirmed by reviews: “I upgraded from the R9 to the R12 and had to turn the sliders down – it was too strong, but now I feel like I'm not missing anything, I get 100% of the detail.” That’s the essence of the R12 – full detail and power within sensible limits.

MOZA R16 V2 – 16Nm of pure power for professionals

Characteristic

MOZA R16 V2 is MOZA’s top-tier base, second only to the R21. The second generation (V2) brings the R16 into the ranks of the most advanced designs on the market. With 16 Nm of torque, it's a high-performance device comparable to the Fanatec DD1 (20 Nm) or Simucube 2 Pro (17 Nm) . The first R16 was known for its aggressive design and excellent build quality, and the V2 version adds maximum functionality to the mix.

First and foremost, R16 V2 features a full range of rear ports – allowing you to directly connect MOZA pedals , sequential shifter , handbrake , cockpit display (Dash) , and the E-stop safety switch . This makes the base the central hub of your simulator – with a single USB cable to the PC, the entire MOZA ecosystem connects through the base.

Another upgrade in V2 is the new dual-mode communication system for the steering wheel: wired (via 5-pin slip ring) and wireless at the same time. This means the wheel receives power and signal through gold pins in the quick-release (no batteries, no lag), while telemetry can be transmitted wirelessly for full rotation freedom. This patented system ensures cable-free stability.

In terms of hardware, the R16 V2 retains its powerful brushless motor with 480W peak power, powered by a 36V supply. The encoder delivers 21-bit resolution – pure professional-level precision that results in incredibly smooth and accurate force feedback, even with the smallest forces.

R16 V2 also features an upgraded FFB algorithm (Force Feedback 2.0), enhancing effects like loss of grip or weight transfer with even greater clarity and depth of detail.

For whom?

16 Nm is territory for true enthusiasts and professionals. If you're competing in serious simracing leagues, training for real-world motorsport, or simply want the best available, R16 V2 is for you. With 16 Nm of torque, it can simulate even the most extreme situations: unassisted steering in a heavy race car, high aerodynamic loads in an LMP1 at 250 km/h, or brutal suspension kicks in WRC on rocky roads.

This base delivers it all with headroom to spare – you’ll often end up lowering the FFB strength in software to avoid fatigue. A key aspect here is control and power reserve. With such a wide torque range, the R16 V2 can generate subtle forces with incredible precision – because it uses only a fraction of its capacity. It’s like driving a powerful car: you don’t always need to hit 250 km/h, but the performance is there if you want it. Likewise with R16 – centering forces in a chicane or fine road vibrations feel ultra-smooth, as the base operates far from its limits.

R16 is also a future-proof choice: you’re unlikely to ever say “I need more power.” Many users choose the R16 over the R12 specifically for that headroom.

It's important to note, however, that 16 Nm requires a proper sim rig. Desk mounting is out of the question – MOZA doesn’t offer a clamp for the R16 (and rightly so). A stable cockpit with bottom or front mounting options is required. The R16 features four threaded holes at the front, compatible with aluminum profile rigs.

The base itself weighs about 9 kg, so it must be firmly mounted to prevent any movement during intense driving. At this power level, cockpit stability is critical – if in doubt, take a look at the solid rig options from Simrigs .

Driving experience

MOZA R16 V2 is available in similar bundles to the R12 , although in this product class most users prefer to customize their setup. The R16 is compatible with all MOZA steering wheels – and the range is impressive. For example:

MOZA Vision GS – a modern wheel with a built-in display and microfiber grips, perfect for the R16.
MOZA Lamborghini GT3 Wheel – a licensed replica of the Lambo Essenza SCV12 wheel, pairs beautifully with the R16.

Of course, more affordable models like the MOZA KS or MOZA CS V2P also work perfectly fine, but most R16 buyers tend to go with premium wheels.

Simline also offers a ready-made R16 + Vision GS bundle – a very attractive high-end combo.

For the R16 base, we strongly recommend top-tier pedals. If you want to stay within the MOZA ecosystem, consider:

MOZA CRP2 (Club Sport Pedals) – high-end load cell pedals.
MOZA Active Pedals – innovative mBooster active pedals, the future of simracing.

Many users pair the R16 with Heusinkveld Ultimate or Simtrec pedals – at this level, it makes sense to invest in high-end solutions to maintain overall balance.

Don’t forget about safety. The Emergency Stop Button (E-Stop) is an important accessory, especially at 16 Nm of torque. The R16 V2 features a dedicated port for the E-Stop, allowing you to instantly cut power in case of a game crash or uncontrolled oscillations – a valuable safety feature.

Sets and kits

Simline sells the R9 V2 and R9 V3 both individually and in bundles with various steering wheels. Available options include: R9 + KS (GT-style, butterfly shape, 300 mm), R9 + CS V2P (round 330 mm, mid-range), R9 + RS V2 (premium round wheel with LED display), or R9 + FSR Formula (fully professional F1-style wheel with screen). These combinations allow you to tailor your setup to your driving style: drift and rally fans will appreciate the large round wheels (CS or RS) for a solid grip and wider rotation; GT3 lovers should go for the KS bundle (GT-style, flat bottom, ergonomic button layout); and F1 enthusiasts will enjoy the FSR2 bundle with butterfly shape and paddle clutches.

Of course, all wheels can also be purchased separately – the R9 base is compatible with all MOZA V2-generation rims, both wireless and wired. For example, MOZA GS V2 (12 buttons, carbon paddles) or MOZA FSR2 work without any adapters. Notably, older MOZA V1 wheels (e.g., GS V1) are also supported by R9 V2/V3 – the brand has maintained backward compatibility, with the exception of the budget ES wheel which requires at least a V2 base.

Also worth mentioning are the more exclusive steering wheels in the lineup, such as the MOZA Vision GS or the licensed gem – MOZA Lamborghini Squadra Corse Essenza SCV12 .

Driving impressions and opinions

MOZA R16 V2 is a base that offers unmatched dynamics and precision. With 16 Nm of torque, the R16 can go from subtle resistance to full-force kickback in a fraction of a second. In a sim, you’ll feel it clearly during oversteer corrections—small grip shifts cause slight wheel tremors, but when the car snaps back into grip, the R16 instantly reacts with full strength, accurately simulating real steering behavior.

This range and response speed give a huge advantage in car control. Drivers using the R16 often highlight that "I can finally feel the grip limit as if I were driving a real car." Especially in cars with high aero downforce (formulas, prototypes), a powerful base makes a real difference—at 250 km/h, even a power-assisted real car becomes heavy to steer, and the R16 replicates this perfectly. Weaker bases often rely on artificial filters to mimic this sensation.

Precision and Detail Reproduction

The R16 also delivers excellent high-frequency feedback. For example, driving over curbs in iRacing creates subtle suspension vibrations—its 21-bit encoder and rigid design transfer those effects clearly, giving the driver richer information through the wheel.

It's worth noting that MOZA R16 V2 (like the R21 ) includes an Ultra Low Static Torque mode—motor optimization that nearly eliminates cogging (notchy feel from magnetic poles). This makes the wheel turn incredibly smoothly when no FFB effects are active. This is crucial in scenarios like simulating a stalled car or neutral situations—resistance only appears when it should.

Advanced Configuration with Pit House

Despite its power, the R16 V2 remains extremely precise and subtle, responding accurately to track events. FFB settings are highly customizable via the MOZA Pit House software, which includes full FFB strength adjustment, damping filters, and an advanced frequency equalizer. This lets you amplify road feel while reducing centering force at high speeds.

Pit House also lets you save presets for different games and vehicles and adjust settings mid-race using the MOZA mobile app.

Is 16 Nm Too Much?

Not everyone will use the full 16 Nm—many users admit they run their R16 at 50–60% because full power is physically demanding. However, that torque headroom ensures you get all the detail even at lower settings.

Also worth noting: the R16 produces some heat and fan noise—comparable to a quiet PC fan under load. It’s not bothersome with headphones, but in a silent room, you may hear a slight hum. Still, the efficient cooling system ensures stable performance even during a 24-hour Le Mans race—there’s no throttling or FFB drop.

Summary

MOZA R16 V2 is professional-grade gear. It offers absolute control and realism, but also demands a solid setup—like a sturdy cockpit and quality accessories. In return, you get a base that can confidently compete with the best on the market—often at a more accessible price point.

Power and Precision at the Highest Level

Many reviewers emphasize that the R16 V2 has closed the gap with brands like Simucube and VRS—MOZA has refined its force, build quality, and compatibility. If you aim for the top tier, but 21 Nm is too much, the R16 will meet virtually every need.

It's an excellent choice for GT3, LMP, Formula, and truck simulator drivers (although even the R9 would be enough in that case). But if you want to feel the full 40-ton load of a truck through your hands, 16 Nm does the job perfectly.

R16 V2 – Refined from the Start

Finally, it’s worth mentioning that the community highly praises the R16 V2 – it’s a fresh model (launched in December 2023), but it has already earned recognition for its improvements over the V1 and a highly polished design from the get-go.

MOZA Pit House – Full Setup Control

Unlocking the full potential of the base is the MOZA Pit House software, which allows precise adjustment of force feedback strength, damping filters, and extra settings like the frequency equalizer. This gives every driver the ability to tailor the FFB feel to match their preferences and driving style.

MOZA R21 V2 – 21 Nm extreme for racing simulators

Characteristic

MOZA R21 V2 is the ultimate flagship – a wheelbase delivering up to 21 Nm of peak torque, built for the most demanding racing simulation setups. It’s one of the most powerful direct drive wheelbases available on the consumer market.

Power That Goes Beyond Typical Sim Racing

21 Nm exceeds the torque found in most modern race cars with power steering — it’s a level typically used to simulate classic F1 cars or large trucks without assistance. R21 V2 is often referred to as “the beast” in the sim racing community.

Cutting-Edge Technology and Top-Tier Engineering

In terms of construction, R21 V2 is very similar to the R16 V2 – sharing the same body, design, and most internal electronics. The key differences are the motor (21 Nm vs. 16 Nm) and a more powerful power supply (around 550 W peak consumption).

Just like the R16 V2 , the R21 V2 features 5 accessory ports, a dual-mode slip ring (wired + wireless wheel connectivity), and the latest FFB 2.0 algorithm. It also uses the same 21-bit encoder with 2,097,152 points of resolution per revolution — meaning the precision and responsiveness are identical to the R16, with the difference lying in maximum torque.

Advanced Cooling and Motor Optimization

R21 V2 weighs slightly more (~9 kg) and features upgraded cooling—internal heatsinks and active fans—to handle the increased heat output at full power.

MOZA also highlights the use of a triple skewed magnet layout in the rotor to eliminate vibrations and torque ripple. Combined with a high copper fill rate in the motor windings, this design achieves both immense power and smooth operation.

Safety Features

R21 is equipped with all essential safety functions: hands-off detection, emergency stop (when connected to the optional E-stop button ), and advanced thermal management for maximum reliability under extended load.

For whom?

MOZA R21 V2 is designed for professional simulators and the most dedicated enthusiasts. Simply put – most sim racers don’t need 21 Nm, and many wouldn’t want to use that level of force on a daily basis. However, there are scenarios where the R21 truly shines:

Where Does 21 Nm Truly Excel?

Truck and bus simulators – large wheels and immense forces – R21 replicates the experience effortlessly.
Sim setups for real-world racing drivers – some pros train with very strong FFB to build strength during off-season.
Virtual reality and full-immersion setups – 21 Nm guarantees no detail is lost due to FFB limitations.
Extra-large steering wheels – R21 handles 350–400 mm rims with ease, ideal for rally and truck sims.

Raw Power Meets Precision

The larger and heavier the steering wheel, the more torque is needed to replicate realistic forces. 21 Nm provides a massive reserve even for 400 mm rims used in heavy vehicle simulations. In real-world terms, every vibration or counterforce will be delivered with total clarity.

This Level of Power Requires a Rock-Solid Mount

Choosing the R21 means you must have an extremely sturdy cockpit. This wheelbase can apply forces capable of damaging weaker frames — you’ll need 80/160 aluminum profile rigs at minimum, or professional rally-grade stands.

The R21 must be hard-mounted – either from the bottom or the front (just like the R16). For best results, we recommend the MOZA Front Mount – a steel bracket for the R16/R21 that allows rigid front mounting with tilt adjustment.

Sets and equipment

MOZA R21 V2 is a wheelbase for those who refuse to compromise. It's designed for the most demanding sim racers and professional drivers building top-tier setups.

Custom Builds – R21 Wheelbase Bundles

Due to its high torque, the R21 is most often purchased standalone, allowing users to pair it with the best available accessories. Simline offers the base alone or as part of bundles with top-tier steering wheels:

MOZA R21 + GS V2P – a premium-class GT wheel.
MOZA R21 + FSR Formula – a high-end bundle for formula racing fans.

Accessories Worthy of 21 Nm

With the R21, there’s no room for half-measures — it’s typically paired with top-tier steering wheels (GS V2P, RS V2, FSR Formula) and high-end pedal sets like:

MOZA CRP2 – top-tier load cell pedals.
MOZA mBooster (active pedal) – an innovative pedal system.
Heusinkveld Ultimate+ – professional hydraulic pedals.
SIMTAG – elite-class hydraulic setups.

For Professional Use

In the case of the R21, it’s worth noting that MOZA collaborates with several racing teams by supplying professional training simulators. The R21 base is at the heart of these systems thanks to its power and reliability. If your goal is to build a training-grade simulator or simply own the most powerful wheelbase around, the R21 is the ultimate choice.

Driving impressions

MOZA R21 V2 is a no-limits wheelbase – delivering not just extreme 21 Nm torque, but also the highest force feedback quality available.

What is it like to drive with 21 Nm?

In short: it feels like driving a real race car with no compromises. While the R16 already delivers impressive 16 Nm, the R21 pushes things even further. In practice, most users will dial the force back for comfort, but having this power reserve results in unmatched signal clarity.

MOZA R21 delivers exceptional feedback purity. The ultra-high resolution encoder and absence of cogging artifacts ensure you feel exactly what the simulation intends – nothing more, nothing less. Even the smallest nuances are captured. R21 offers slightly better “direct connection to the car” feeling than R16, likely due to its stronger holding torque at low signal strength.

Is 21 Nm too much?

With dynamic effects, it's hard to utilize the full power – even 16 Nm can try to pull the wheel out of your hands. So is it necessary? Opinions vary – some simracers say it's overkill and prefer lighter settings, while others enjoy the “wrestling” feel – for them, R21 is a dream come true.

Technically, the R21 V2 shares all the advantages of the R16 V2 – it's ultra-smooth, fast, and latency-free. It features the same Smart Cooling, Hands-Off Detection, and other safety systems. You'll feel the difference mainly in extreme moments, or if you deliberately run FFB at 100%.

R21 in action – extreme power in simulation

?️ In AMS2 – an 80s F1 car (no power steering) with 100% FFB on R21 will challenge your strength in corners just like the real thing.
? In Euro Truck Simulator 2 – maneuvering a 40-ton rig, feeling the weight through the massive wheel – an unforgettable experience for realism lovers.

In summary: R21 V2 delivers raw power and best-in-class force feedback. Even if you won’t use the full 21 Nm daily, the headroom guarantees that every force feedback effect is cleaner, stronger, and more realistic.

Safety and attention

When dealing with 21 Nm, safety must be a top priority. MOZA R21 is a powerful wheelbase that can be dangerous if not used properly. Always securely bolt the base down and double-check that your steering wheel is correctly locked into the quick-release (MOZA thankfully uses a safe and robust QR mechanism). It's also recommended to wear gloves and maintain a firm grip – letting go of the wheel under full FFB can trigger intense oscillations. The system does detect and stop them, but there can still be a sudden jolt for a split second.

That's why you should always connect the Emergency Stop button to your R21 base – (Emergency Stop) is a mushroom-style button that cuts the power to the base instantly. In emergencies (like a game glitch causing the wheel to spin uncontrollably), pressing it stops everything immediately. This is standard for bases above 15 Nm, and MOZA includes a dedicated E-stop port at the rear of the unit.

On the software side, MOZA Pit House allows you to limit the maximum force – you can set it to 75% and use the R21 like an R16 – but with even higher precision. That said, the R21 V2 is already a polished product, leaving little to improve in terms of both raw power and overall refinement. MOZA continues to push forward – now including 360Hz FFB refresh rate support in iRacing, for example.

Summary

MOZA R21 V2 is a choice for the few but demanding. If you’re among those who seek maximum realism and aren’t afraid of serious torque – this is the hardware for you. Otherwise, it’s better to stick with something like the R16 or below, because the R21 only shines in specific scenarios. That said – owners of the R21 usually don’t regret the investment. You get a device that takes simulation to the next level and will remain technologically relevant for many years.

The R21 is often described as “future-proof” – after all, what more could you need than 21 Nm of torque and top-tier precision? Perhaps only more advanced steering wheels or pedals, but the base itself remains the heart of the system. By choosing R21 V2, you’re joining an elite group of simracers with the kind of power that until recently was reserved for professional racing teams.

Choosing the right steering wheel and pedals for your driving style

If you already own a MOZA base (regardless of the model), it’s worth choosing the right steering wheel (rim) and pedals for your favorite driving style. MOZA, together with simline.eu, offers a wide selection of steering wheels – from simple drift rims to GT3 and F1 replicas – as well as various pedal sets. Here are some recommendations tailored to specific use cases:

For drifting and rally – The best choice here is a round steering wheel with a larger diameter and a solid grip. In drifting, you often spin quick “counter-steers,” so a 330–350 mm wheel is useful, even with a “dish” (deep dish) design for better control. In MOZA’s lineup, a great choice is the RS V2 wheel (330 mm diameter, round, leather-wrapped) or the more affordable CS V2P (320 mm). Both are robust and have a classic shape – perfect for controlled slides and fast hand transitions.

In rally driving, a sequential shifter and handbrake are also key – MOZA offers the SGP shifter and HBP handbrake, which can be connected directly to the base (V2 versions support a single-cable setup).

Pedals: drifters and rally drivers often prefer light and quick pedals – the two-pedal MOZA SR-P Lite set (gas and brake, no clutch) can be enough to get started. However, for better braking control (especially trail-braking in rally), a load cell brake is recommended. The MOZA SR-P with a 100 kg sensor offers better feel and control – it’s easier to find the locking threshold, which is crucial on loose surfaces.

Drift/rally is a noisy and aggressive style, so bases like the R9 or R12 are optimal – they provide enough strength for fast steering inputs. Too powerful of a base like the R16 or R21 can make things more difficult on loose surfaces due to their extreme feedback. Still, if you love realism, you can drift with the R16 – just be careful with your hands!

For GT / prototype racing – In GT3, GT4, LMP, or even road-going hypercars, the most important factors are steering wheel precision and ergonomics. A great pick here is a GT-style wheel with a slightly flat bottom or an ergonomic “D” shape. MOZA’s KS Steering Wheel is a solid choice – 300 mm, “butterfly” design, resembling modern GT car wheels. It features durable magnetic shifters and is made of carbon fiber and leather, striking a good balance between weight and realism.

A higher-end alternative is the MOZA GS V2 / GS V2P – a premium 330 mm GT wheel with better build quality (microfiber grips, more buttons, clutch paddles), but also heavier and more expensive. For LMP prototypes or modern hypercars, you might consider the MOZA Vision (GS with display) or SimLine’s custom replicas – such as their Huracán GT3 or AMG GT3 rims.

Pedals: Braking precision is crucial in circuit racing. At minimum, a 100 kg load cell brake is recommended – ideally even a hydraulic simulator. The MOZA SR-P is great for amateur racing (16-bit encoder and firm elastomer-based brake). If budget allows, check out the MOZA CRP2 – an upgraded pedal set with even finer modulation.

For GT cars, a third pedal (clutch) is useful, especially if you race manuals – MOZA offers a separate clutch for the SR-P Lite, and the full SR-P set includes a clutch by default.

Base: For GT racing, we recommend at least the R5 / R9, but the more power, the better – GT cars with downforce can realistically exert ~10–12 Nm of torque on the wheel. The R9 delivers immersion, the R12 provides full realism even under heavy aero load, and the R16 / R21 offer extra overhead for the most demanding drivers.

For Formula 1, Formula E, and open-wheel cars – Here, a Formula-style wheel is key: smaller (~280 mm), with multiple buttons and clutch paddles. MOZA offers the top-tier FSR Formula Wheel – a 280 mm rim with OLED display, 10 buttons, encoders, and dual paddles (for shifting and clutch). It’s an ideal choice for simulating F1, F2, Formula E, or even Le Mans prototypes. This type of wheel lets you manage ERS, engine maps, DRS, and more during races, while the compact diameter mirrors real-world single-seaters (which have extremely direct steering ratios).

If the FSR is out of budget, you can consider more affordable Formula wheels from other brands (e.g., Cube Controls or VNM) with an adapter – though you may lose some integration. Another MOZA option is the GS V2 – technically a GT wheel, but widely used in Formula too. Its 330 mm diameter is larger than typical F1 rims, but it still features a rich control layout and good grip.

Pedals: Load cell or hydraulic pedals are a must. Simulating F1 braking requires a very stiff brake pedal (real F1 cars can demand ~100 bar of pressure). You’ll want pedals that can withstand and accurately reflect high input forces. We recommend the MOZA CRP2 – their latest premium pedal set built for high-level racing applications.

Wheelbase: The more powerful, the better. With 1:1 settings, F1 sims can generate over 15 Nm during high-speed driving (since real F1 cars without power steering have ~15–20 Nm torque). For full realism, the R16 or R21 are ideal. The R9 can also do the job, but you'll need to scale down the strength – it still provides excellent feedback, just at lower force levels.

Formula racing also demands quick and precise response from the base – this is where the R16 and R21 shine thanks to their high-resolution encoders (21-bit) and strong motors, delivering micro-detail feedback in high-G corners. Many F1 simracers using VR especially appreciate the R21’s ability to realistically replicate unassisted steering forces, helping them better understand car behavior.

Summary: For F1 sims – choose the FSR wheel, CRP2 pedals, and a base of at least the R12, ideally the R16+.

For truck, bus, and heavy machinery simulation (ETS2, ATS, OMSI) – More and more people are using sim racing platforms for utility vehicle simulation. Here, the priority is a large steering wheel and high torque, though you don’t need a lot of buttons or carbon fiber. For this purpose, MOZA created the R5 Truck Bundle – it includes the R5 base and a large 400 mm round steering wheel styled after a real truck wheel. This allows for wide, slow steering inputs, just like in a real rig.

While 5.5 Nm may seem low, it’s actually more than enough for truck sims (modern trucks with power steering rarely exert more than a few Nm on the wheel). If you want to simulate an old Kamaz with no power steering, then R21 will deliver the brutal realism – but that’s an extreme use case. For standard ETS2/ATS gaming, the R5 or R9 are more than enough.

The wheel is more important – MOZA offers a dedicated truck-style wheel: MOZA TSW. You can also add immersion with the multi-function stalks for indicators or cruise control.

Pedals: In trucks, a clutch is important, and the brake is often soft (air brakes). The MOZA SR-P Lite with the clutch add-on is a good match (3 pedals, not too stiff). You don’t need a precise race-style brake here – a load cell isn’t necessary, though SR-P with load cell will also work fine if set to a softer curve.

For farming or construction sims (e.g. Farming Simulator, Construction Simulator), similar principles apply – a large wheel and moderate FFB are ideal.

Noise: Note that R5 and R9 are very quiet, which fits the relaxed vibe of truck sims. Meanwhile, R16 and R21 have fans that might hum unnecessarily during chill drives. So again, R5 or R9 are the smart choices for this category.

For versatile use (a bit of everything) – If you plan to use your setup for a wide range of games (from F1 to rally to truck sims), it’s smart to go for a flexible configuration. A great solution is to have two wheels: one round wheel like the CS V2P or RS V2 for drift, rally, and truck driving, and a second GT/formula-style wheel like the KS or FSR for track racing. Thanks to MOZA’s quick release system, swapping wheels takes just seconds.

As for pedals, it’s best to go straight for a 3-pedal set with a load cell – this gives you full capability for both race cars (where a stiff brake is essential) and trucks (where you need a clutch). The MOZA SR-P (3-pedal set) offers excellent price-to-performance for all-around use.

Base: The R9 stands out as the perfect balance – strong enough for sim racing, yet compact and affordable enough not to overdo it for more relaxed games. If your budget allows and you want long-term peace of mind, the R12 V2 is also a fantastic all-around choice, offering extra power and the latest standards.

The R16 and R21 are more suitable for users who spend most of their time in high-demand sims (e-sports leagues, professional training). For the typical enthusiast who might drive rally today, Formula tomorrow, and a truck the day after, the R9 or R12 will be more than enough.

Practical tips: noise, assembly, simrig

To wrap up, here are a few practical observations about using MOZA wheelbases on a daily basis:

Noise and Cooling:

Smaller bases (R3, R5, R9) are very quiet. R3 and R5 have passive cooling or small fans that are practically inaudible. R9 features an active fan, but it only turns on under heavy load – during driving it’s masked by in-game engine sounds, and when idle, it emits a gentle hum, if at all.

Larger models like R16 and R21 use more robust active cooling. The rest of the wheelbases are passively cooled via their cases, so they don’t generate noise.

R16 and R21 produce the most heat – their fans can spin at higher speeds, especially in summer. However, users report the noise is not intrusive and comparable to a gaming PC under load. If you’re using headphones or speakers, it’s barely noticeable.

Important: Never block the ventilation holes. Make sure there’s airflow around the wheelbase – especially for R16/R21, where air needs to flow through the side radiator fins and the rear of the unit.

One advantage of MOZA’s active cooling system is that the base doesn’t reduce power output – even if the casing feels warm, algorithms ensure full 16 or 21 Nm torque is maintained without throttling. Unlike some older systems, MOZA won’t “cut” your FFB halfway through a race due to overheating, which is a big plus. (See: MOZA Racing R21 Direct Drive Wheel Base)

As for mechanical noises – direct drive bases are generally quiet, although you may hear subtle sounds (like a faint servo hum) during fast wheel movement. MOZA uses features like skewed windings to reduce cogging and prevent buzzing. The result? Acoustically smooth operation – no “grinding” or rattling noises.

With extreme software filter settings (like adding artificial vibrations), you might hear a coil whine, but this is rare. Overall, MOZA wheelbases are considered quiet and refined in sound, so you don’t have to worry about disturbing others at home – unless you spin out and start wrestling the wheel, which could cause some thuds from the bump stops. But that’s part of the fun.

Mounting and Stand Requirements:

As mentioned earlier, bases like R3, R5 (and optionally R9 / R12) support desk mounting. If you don’t have a cockpit but want to start with direct drive, the MOZA R5 bundle is one of the few kits on the market that lets you race from your desk straight out of the box.

The MOZA Clamp is made of steel, features tilt adjustment, and fits desks up to 5 cm thick. Be sure to tighten it firmly using Allen screws (not quick-release levers), as direct drive generates more torque than, say, a G29 – you don’t want your base sliding around.

MOZA offers two types of clamps: a basic version (included with the R5 bundle) and an advanced one sold separately – more adjustable, compatible with R5, R9, and R12. If you’re driving aggressively on a desk with an R9, consider the higher-end clamp – it’s sturdier and allows better angle adjustment for ergonomics.

For bases from R9 and up, a cockpit is strongly recommended. Owners of R16 and R21 will find it essential. Even R9 can cause desk resonance during sharp movements, so if possible, invest in a stand (like a Wheel Stand Pro or an entry-level profile cockpit).

MOZA R9, R12, and R16 use a standard bottom mounting pattern (4x M6 bolts, 52x66 mm – same as Fanatec and others). Additionally, R16 and R21 have four front-mounted holes for vertical plate mounting (front mount). The MOZA Front Mount Adapter is an aluminum bracket you screw into the front of the base to secure it to your rig (like 8020 aluminum profiles). This helps especially when your cockpit lacks height adjustment from below and frees up legroom.

In general, with R16 and R21, front mounting is preferred due to the high forces that can “pull” the base downward – front mounting mitigates this and protects the bottom threads. With R9 and R12, bottom mounting is usually sufficient.

Your rig should be as stiff as possible. The less flex, the better the force feedback translates through the system, giving you more precise feel. If your cockpit has play or flex, R16 will expose it – even the best base can’t perform to its full potential if the rig bends instead of transmitting FFB cleanly.

That’s why owners of R16 / R21 often invest in professional-grade rigs (like those from RECART). For R9 or R12, something like a Huzaro stand or a 40x40 profile rig will do just fine.

Power Supply:

MOZA wheelbases use external power bricks. The R5 comes with a compact 120W adapter, R9 uses ~180W, R12 ~280W, and R16 includes a hefty 360W adapter (laptop-style, just larger). The flagship R21 packs a massive 480W power supply — think gaming laptop PSU on steroids.

Make sure the power adapter has good ventilation, especially with R16 / R21 — don’t cover it with clothes or stash it inside an enclosed cabinet. These get fairly warm under load.

The cable length is typically sufficient for routing through your rig. If needed, you can use a DC extension cable — preferably a branded one to avoid voltage drop.

Connection to the PC is via USB — Type B (printer-style) port on R5 / R9, and also used in newer R12 / R16 / R21. (Unlike Fanatec which sometimes uses USB-C, MOZA has stuck with the tried-and-true USB-B).

Pro tip: Plug your base directly into a USB 3.0 port on the motherboard — not through a USB hub. Direct connection reduces potential latency or interference. MOZA Pit House is quite sensitive — it may display a warning if a weak USB signal is detected.

Software & Updates:

Installing MOZA Pit House is straightforward, and the interface is clean and intuitive. It’s highly recommended to update the firmware for your wheelbase and steering wheel right after installation — MOZA frequently rolls out updates that improve FFB or introduce new features. The update process is automated within the app (Settings tab). Just remember: do not power off during firmware flashing.

Pit House also features an auto-calibration mode — when you power on the base, the wheel will perform a full spin to calibrate center position (this is normal). Avoid holding the wheel during startup, as MOZA bases may perform a full rotation. The same applies after a firmware update — expect movement.

For daily use, check out community-shared FFB profiles — on forums or MOZA's official Discord, users often share settings for specific games. This saves time versus tweaking sliders from scratch — you can load a preset and adjust to your liking.

Game compatibility is excellent — MOZA works with nearly all major PC sim titles. Some games (like AMS2 or rFactor2) may require manual setup of steering angle and linearity, but those are minor details.

Overall, Pit House supports auto-rotation — games can automatically set the steering lock (e.g., 900° for rally, 360° for F1) — and this feature works reliably. If a game doesn’t support it, you can easily change rotation angle manually in the app.

Handling & Safety:

Direct drive systems require a bit of caution — never leave the base powered on unattended, especially the high-torque ones. It’s best to turn off the power after each session (via the rear power button or a power strip). This prevents unexpected behavior if a game accidentally launches.

Always check that the steering wheel is securely attached to the hub — MOZA uses a convenient aviation-style Quick Release with a twist-lock ring, which is generally very solid. Still, make sure the ring is fully tightened and locked in place — a loose connection can cause knocking and wear down the interface faster.

If you're using a MOZA R9 or stronger base, it's especially important to occasionally double-check that everything is firmly secured.

It’s also a good idea to check the bolts fastening the base to your rig from time to time — the intense forces can slightly loosen them over long sessions. Using spring washers or thread locker can solve the issue if it’s a part you don’t intend to remove often.
