iRacing FFB Settings: Fanatec, Moza, Simucube & Logitech

iRacing’s force feedback works differently from every other sim. There’s no “FFB volume” dial. Instead you set Wheel Force to your base’s Nm output, hit Auto on each new car to calibrate per-car Max Force, and let the telemetry speak. Get those two settings right and iRacing communicates tyre slip and limit grip as well as any sim on the market. Get them wrong and you’ll clip permanently, run lifeless straights, or break your wrist on a crash spike. This is the per-brand baseline for every major wheelbase, current to 2026.

How iRacing force feedback works

iRacing’s FFB outputs the actual forces acting on the virtual steering column. No canned effects, no synthesised chassis tricks. That’s why it’s the bedrock of the competitive scene. The trade-off: it expects you to dial in two settings per base and one setting per car.

Wheel Force (per base) tells iRacing what your hardware can deliver in Nm. Match it exactly to your base’s peak output. CSL DD at 8Nm, ClubSport DD at 12, Podium DD2 at 25, T818 at 10, G PRO at 11, and so on. This is the safety ceiling for crash spikes and the reference iRacing uses to compute Max Force per car.

Max Force (per car) is the value iRacing’s on-screen FFB bar measures against. It’s the steering-column torque telemetry value at which your base maxes out for that specific car. Higher Max Force = LIGHTER wheel, because you’re telling iRacing “don’t max out my hardware until the telemetry hits this number”. The “Auto” button calibrates Max Force after a clean lap so peak telemetry exactly matches your hardware peak. Map a button to it and use it on every new car. After Auto, a GT3 typically settles around 35-45 Nm regardless of base.

Use Linear Mode is the third key call. CHECKED for direct drive (you want 1:1 raw telemetry). UNCHECKED for sub-8Nm belt or gear bases (you want the low end boosted so you can actually feel slip on a G29 or T300). iRacing made Linear the default in 2018, which is right for DD but a step backwards for older Logitechs and the T300.

The rest is base-specific. If you want the wider picture, the direct drive wheel settings hub covers brand-by-brand for every sim, and the FFB explainer walks through what each slider does. This page is the iRacing-specific matrix.

One more 2026 note: iRacing’s native 360Hz FFB output has caught up enough that irFFB (the long-running third-party FFB layer) is no longer mandatory for direct drive bases. It’s still useful for belt and gear users who want to add calculated self-aligning torque cues that native iRacing intentionally omits – the “irFFB2026” branch is what to look for.

Fanatec settings for iRacing

Fanatec on iRacing is the most documented combo in the sim. Maurice Böschen’s Fanalab profiles are the gold standard – he updates them per major iRacing build and the Fanatec official forum thread mirrors the Tuning Menu values. FFS on Peak (rather than Linear) is the call most people miss on the CSL DD and Podium bases. On the ClubSport DD and DD+ the firmware unifies that toggle, so it doesn’t appear in your menu.

Fanalab / Tuning Menu (covers CSL DD 5Nm + 8Nm, ClubSport DD 12Nm, ClubSport DD+ 15Nm, Podium DD1 20Nm, Podium DD2 25Nm):

The single biggest improvement most Fanatec iRacing users can make is loading Maurice’s per-car FanaLab profiles rather than running a single global setup. Each car’s Auto-calibrated Max Force gets saved to the profile and re-applied automatically.

Moza settings for iRacing

Moza’s Pit House defaults are too aggressive on Road Sensitivity for iRacing – the iRacing telemetry signal is already detailed, you don’t need amplification on top. Pull it to 9-10 and let the in-game Wheel Force do the headline work. Mechanical Damper rises with base torque, which is the right move: a 21Nm R21 needs more damping to catch crash spikes than a 5.5Nm R5 ever will.

Pit House (R5 5.5Nm, R9 9Nm, R12 12Nm, R16 16Nm, R21 21Nm):

The R5 in iRacing will clip noticeably on a kerb hit at a GT3 pace – that’s inherent to a 5.5Nm base running a 45Nm telemetry car. Live with it or step up. For the wider Moza range see our Moza buyer’s guide, and the per-base companion is Moza FFB settings for iRacing.

Simagic settings for iRacing

Note the key Simagic difference between iRacing and AC: Wheel Return Speed stays at 100 for iRacing, not 0 like AC. iRacing’s caster trail simulation works fine with the assist on, and turning it off here makes the wheel feel sluggish to centre. The other thing to watch is Smoothness – drop it to 0 on the Alpha U so the 360Hz telemetry passes through unfiltered.

Simucube settings for iRacing

Simucube on iRacing is the gold-standard combo at the top of the sim, partly because Daniel Morad and Dan Suzuki publish curated TrueDrive profiles via the Paddock cloud. Overall Strength stays at 100 in TrueDrive, Reconstruction Filter at 3 is the sweet spot (1 for absolute raw, 5 for heavy smoothing on rough kerbs), and the in-game Wheel Force matches your base’s peak Nm.

Logitech settings for iRacing

Logitech splits cleanly. The G29, G920 and G923 are gear or belt drive at 2-2.5Nm peak with a real mechanical deadzone around centre – they need Use Linear Mode UNCHECKED and Min Force at 10-15% (or better, a custom LUT generated via WheelCheck and routed through irFFB). The newer DD G PRO (11Nm) and RS50 (8Nm) follow the DD rules: Linear ON, Min Force 0, Wheel Force matches the base Nm.

Max Force GT3 (Auto)~20-25 Nm~22-28 Nm~28-35 Nm~38-45 Nm

If you own a G29, G920 or G923, the irFFB + custom LUT route is the upgrade. Run WheelCheck to log your specific unit’s mechanical deadzone, feed it into the LUT Generator, and irFFB will spike the voltage exactly when needed to bridge the slack. Min Force can then go back to 0 and the wheel feels honest. Our G923 iRacing settings page goes deeper on this.

Thrustmaster settings for iRacing

Two completely different setups. The T300 RS belt-drive needs the Overall Strength capped at 75% in the TM Control Panel to avoid thermal fade after 30 minutes of racing – this is the most common T300 complaint and the easiest fix. Force the internal fan to stay on (Mode + Option/Start until the light flashes twice). For iRacing, untick Linear Mode and run a tiny Min Force to bridge the belt’s centre slack. The T818 DD is the opposite – all sliders at 100, Linear Mode on, Min Force 0.

Common mistakes in iRacing wheel settings

  • Never hitting Auto per new car. The biggest single mistake. Max Force is per-car telemetry, not a global setting. Map a button to Auto, drive two clean laps, hit it. Repeat on every new car.
  • Min Force above 0% on a direct drive. DDs have no mechanical centre slack. Any non-zero Min Force causes a robotic rattle on straights. Set it to 0.
  • Min Force at 0% on a belt or gear wheel. The opposite trap. G29, G920, G923 and T300 have a real mechanical deadzone. Run 1-15% Min Force or, better, a WheelCheck-generated LUT through irFFB.
  • Wheel Force way higher than the base’s real Nm peak. Setting Wheel Force to 25Nm on a 12Nm CSL DD doesn’t make the wheel stronger. It removes the safety ceiling and risks injury on a crash spike when iRacing demands more torque than the hardware can deliver.
  • In-game Damping above 0% when the base software’s Damping is already on. The signal double-dips through two filters. Set in-game Damping to 0 and control weight via TrueDrive, Fanalab, SimPro Manager or Pit House only.
  • Use Linear Mode the wrong way round. Ticked on a Logitech G29 makes the low-end forces disappear. Unticked on a Simucube Pro adds an artificial high-end ramp that masks tyre slip. Rule: DD = ticked, sub-8Nm belt/gear = unticked.
