If you’ve got a Moza base and you race in iRacing, there are two pieces of software to set up, MOZA’s Pit House and iRacing itself. In today’s post we’re taking a look at what MOZA’s own guide and its R5 video suggest for Pit House, what iRacing’s June 2025 Moza update means for 360 Hz and Wheel LFE, and the settings iRacing asks for in the game.

What iRacing does with a Moza base

MOZA’s own support page says iRacing’s force feedback doesn’t need any configuration in Pit House, and as long as Pit House is open it picks up iRacing’s telemetry automatically.

iRacing’s 2025 Season 3 build (June 2025) updated the Moza API, which added Wheel LFE and 360 Hz mode. Wheel LFE (low frequency effects) sends engine, kerb and slip vibrations through the wheelbase motor, the way a bass shaker would. 360 Hz packs six of iRacing’s physics samples into each 60 Hz force feedback update, so the update rate stays the same and each update carries more data. Both run on every Moza base from the R3 up to the R25 Ultra once you’re on Pit House 1.3.1.50 and base firmware 1.2.5.5 or later, and iRacing switches them on by default.

The current build is 2026 Season 4 (9 September 2026), and none of this year’s release notes mention Moza. The June 2026 update moved the advanced force feedback settings onto their own FFB tab and added per-car control profiles. I’ve written up the general iRacing FFB settings separately, for whatever wheel you drive.

How to use Pit House

Open Pit House and click the wheelbase icon, second down the left-hand side, and you’ll see the wheelbase settings with their tabs along the top, starting with Basic Settings. The Basic tab opens with the Preset panel and an Auto Load Preset toggle. In my January 2026 screenshot below, taken with my R25 Ultra, the loaded preset is MOZA’s R25 Ultra-AC-Official, tagged Official and Assetto Corsa. The buttons along the bottom are Import Setting, Export Preset, Recovery, Save and Save As.

MOZA’s Preset Modes cover GT, Formula 1, Rally, Drift and Trucks, and each one sets several of the FFB settings for that type of car. MOZA says it has found the GT and Formula 1 presets to be particularly well-tuned out of the box.

The FFB settings – what they mean

The definitions below are MOZA’s own, from its Pit House force feedback guide of January 2025, under the names that guide gives each setting. The 1.3.4.56 build in my screenshots lays things out differently. Its Advanced tab, in the screenshot below, lists Natural Damping, Natural Friction and Natural Inertia, and you won’t find Road Sensitivity, Wheel Friction or Speed-dependent Damping under those names on its Basic or Advanced tabs.

• Maximum Steering Angle: How far the wheel turns, lock to lock. For formula-style cars that’s 360°, for GT and sportscars 540°, and for road cars, rally and drifting 900°. Synchronous makes the rotation on the wheel and in the game match.
• Road Sensitivity: How strongly the track surface detail comes through, from 0 to 10. MOZA suggests 8-10 to feel every track detail and 4-6 for a smoother feel with less noise, with GT and Formula 1 cars suiting the higher end.
• Game Force Feedback Intensity: An overall multiplier for the game’s forces. MOZA says turning it down lowers the force without losing any detail, and it suggests 100% on the R3, R5 and R9 and 70-90% on the R16 and R21 for comfort.
• Maximum Output Torque Limit: A hard limit on peak force, useful for cutting jarring impacts. MOZA says 100% is usually fine on the R3, R5 and R9, and suggests 70-80% on the R16 and R21 for sustained racing.
• Natural Inertia: Simulates the weight of the steering column. Higher feels more like a real car, and lower makes the steering faster for quick corrections. GT cars suit 200-300%, and formula cars sit lower, at 100-150%.
• Wheel Friction: A constant resistance to steering. Higher simulates a car without power steering, like a historic car, and lower suits a modern GT race car.
• Speed-dependent Damping: Adds steering weight as the speed rises, the way a real car gets heavier at speed. MOZA’s starting point is around 60%, with activation at 200 km/h.

The FFB Effect Equalizer works like an audio equaliser, raising or lowering particular kinds of feedback by frequency. In 1.3.4.56 its points sit at 10, 15, 25, 40, 60 and 100Hz, and MOZA’s guide splits that range into three bands:

• Low (0-15Hz): chassis movement, roll, weight transfer and suspension compression, generally kept at around 100-120%.
• Mid (15-40Hz): kerb impacts and tyre slip, which you can boost to 150-180% for a better feel.
• High (40-100Hz): road surface texture and tyre vibration, usually reduced to 80-100% to keep the noise down.

Pit House settings from MOZA’s R5 video

The MOZA Racing channel‘s R5 video, from December 2024, has SimRacingPal from the MOZA Creator Program sharing his own settings on an R5 with a 300 mm rim. He keeps Game Force Feedback Intensity at 100% in Pit House, so he isn’t losing any detail, and sets the strength in iRacing instead. Road Sensitivity comes down to 4 because 10 was too harsh for him, while MOZA’s own guide says 8-10 if you want to feel every track detail. Wheel Spring goes to 0 because it tries to pull the wheel back to the centre, and Wheel Damper goes to 0 because it gives the wheel a sense of stickiness. Natural Inertia and Wheel Friction go the other way, to maximum, since at zero the wheel is very light and doesn’t feel natural. These are his Pit House settings, under the tabs the video’s late-2024 Pit House used:

• Basic Settings:
  • Road Sensitivity: 4 (3 with a smaller formula-style rim)
  • Game Force Feedback Intensity: 100%
  • Maximum Wheel Speed: maximum
  • Wheel Spring: 0
  • Wheel Damper: 0
• Advanced Settings:
  • Maximum Output Torque Limit: 100%
  • Steering Wheel Inertia: the preset for your rim
  • Natural Inertia: maximum
  • Wheel Friction: maximum
  • Speed-dependent Damping: 0
  • Force Feedback Curve: linear
  • Soft Limit Stiffness: 5

iRacing in-game settings

In iRacing, these are the options to set on the FFB tab:

• Enable Force Feedback: On
• Use Linear Mode: On
• Reduce Force When Parked: up to you (MOZA’s R5 video calls it personal preference)
• Wheel Force Auto: Off (so you can set Wheel Force by hand)
• Wheel Force (Nm): the base’s rated torque
• Strength: Auto, for each car and each track
• Intensity: 100% in MOZA’s R5 video (iRacing’s default is 50%)
• Smoothing: 0%
• Damping: 0%
• Min Force: 0%

MOZA’s R5 video sets Strength with the Auto button, mapped in your controls. You drive a lap or two and press Auto when it lights up in the F9 black box. iRacing’s own setup guide says Auto often comes out too strong on a big direct drive base, and if yours does, turn Strength down.

Settings for each Moza base

iRacing’s own setup guide says Wheel Force should be the base’s rated torque and never lower, so it changes with every base. MOZA’s guide puts Game Force Feedback Intensity and the Maximum Output Torque Limit at 100% on the R5 and R9, and suggests easing both off on the R16 and R21 for comfort over a long race. It doesn’t mention the R12, so that base only gets its Wheel Force.

• Moza R5 (5.5 Nm):
  • Wheel Force (Nm) in iRacing: 5.5 Nm
  • Game Force Feedback Intensity: 100%
  • Maximum Output Torque Limit: 100%
• Moza R9 (9 Nm):
  • Wheel Force (Nm) in iRacing: 9 Nm
  • Game Force Feedback Intensity: 100%
  • Maximum Output Torque Limit: 100%
• Moza R12 (12 Nm):
  • Wheel Force (Nm) in iRacing: 12 Nm
• Moza R16 (16 Nm):
  • Wheel Force (Nm) in iRacing: 16 Nm
  • Game Force Feedback Intensity: 70-90% for comfort
  • Maximum Output Torque Limit: 70-80% for sustained racing
• Moza R21 (21 Nm):
  • Wheel Force (Nm) in iRacing: 21 Nm
  • Game Force Feedback Intensity: 70-90% for comfort
  • Maximum Output Torque Limit: 70-80% for sustained racing

What about the Moza R25 Ultra?

I own an R25 Ultra and an R21, and I’ve written both up in my R21 and R25 Ultra review. Neither MOZA’s guide nor its iRacing page gives settings for the R25 Ultra by name, so the one fixed number is its Wheel Force of 25 Nm. The nearest MOZA gets is its advice for the R16 and R21, which is 70-90% Game Force Feedback Intensity and a 70-80% Maximum Output Torque Limit for comfort on a long race.

Fine-tuning

If something doesn’t feel right once you’re out on track, start here:

• If your base started buzzing or sounding mechanical after iRacing’s June 2025 update, it’s usually Wheel LFE at its deliberately loud shipped level. You can switch it off with Enable Wheel LFE in iRacing, or turn it down in the [TrueForce] section of Documents\iRacing\app.ini, starting with the continuous channels (Engine RPM and Road Texture).
• When you’d rather not have 360 Hz at all, set enableFFB360HzInterpolated=0 in Documents\iRacing\app.ini.
• If the F meter sits full for long stretches, you’re clipping (the sim asking for more force than your base can give), so turn Strength down until it only fills on the big bumps and kerbs.
• When an R16 or R21 feels too heavy for a long race, drop Game Force Feedback Intensity to 70-90% or the Maximum Output Torque Limit to 70-80% in Pit House.
• If crash and wall impacts feel too jarring, lower the Maximum Output Torque Limit in Pit House, which MOZA says reduces them while keeping the detail.
• If Auto keeps coming out too strong on a big base, lower Intensity before you press it, since Intensity sets how hard Auto pushes.

Whichever settings you start from, Auto sets Strength for one car at one track, so press it again whenever you change either. For other sims, my direct drive wheel settings guide has a Settings Finder, and if you’re still choosing a base, my Moza buyer’s guide covers the range. I’ll see you out on track!
