iRacing FFB Settings
iRacing's force feedback works differently from most sims: you tell it how strong your wheel is in Nm, then set how much car force maps to it. Get those two right and the rest is simple. Values for every major wheel below, with sources.
How iRacing force feedback works
- Wheel Force (Nm): the peak torque iRacing assumes your base can produce. Set it to your base's rated torque. "Wheel Force Auto" tries to detect it but can overestimate, so many drivers turn it off and type the number in.
- Strength: how much of the car's steering force is sent to the wheel. In iRacing the number is in Nm of car force: a higher number means a lighter wheel. Press Auto (in the F9 black box) after a few clean laps and iRacing picks a value that just avoids clipping, then adjust to taste.
- Intensity: only affects the Auto button: 100% gives the strongest feel, lower keeps heavy cars feeling heavier than light ones. Default 50%.
- Use Linear Mode: on for direct drive; off for gear-driven wheels like the Logitech G29, G920 and G923, where non-linear mode boosts small forces.
- Min Force, Damping, Smoothing: 0% on direct drive. Min Force helps weak gear and belt wheels feel small forces.
- Reduce Force When Parked: on, to stop the wheel oscillating in the pits.
The force feedback settings are in Settings → FFB (since the 2026 Season 3 update, the advanced options have their own page). The steering force meter is under Settings → Interface → On-Screen Displays → System Meters.
Set up iRacing FFB in 5 steps
- Wheel software first: load your brand's iRacing profile or the settings below, with no extra spring or damper.
- Set Wheel Force to your base's rated torque in Nm, with Wheel Force Auto off.
- Linear Mode on for direct drive, off for gear-driven wheels. Min Force, Damping and Smoothing 0% on direct drive.
- Drive a few clean laps, then press Auto in the F9 black box to set Strength for that car.
- Adjust: if the wheel is too heavy, raise the Strength number (lighter); if it feels weak, lower it, watching the force meter for clipping. iRacing remembers Strength per car.

Values from wheel makers' published iRacing settings and iRacing's guide, as compiled by SimRacingCockpit (September 2026). MOZA and Simagic publish profiles rather than numbers, so those rows follow the standard direct drive method. Fanatec torque figures from Fanatec's own pages.
Wheelbase software settings
- Fanatec CSL DD (tuning menu): SEN Auto, FF 100, FFS Peak, NDP 15, NFR off, NIN off, INT 6 (other guides use 3), FEI 100, FOR 100, SHO 100. Every setting explained in our Fanatec CSL DD settings.
- MOZA (Pit House): game FFB intensity 100%, wheel spring 0%, wheel damper 0%, max output torque 100%, linear curve.
- Simagic (SimPro Manager): load the iRacing game profile. Coach Dave's preset values and starting Strength per EVO base are in our Simagic Alpha EVO settings.
- Simucube (Tuner): set overall strength to the most you would want in a crash, add a little damping and friction to taste.
- Logitech RS50 / G PRO (G HUB): FFB filter 1, dampener off, TRUEFORCE audio 100, angle 1080°. G29/G920/G923: G HUB defaults.
- Thrustmaster T598 (on the base): master gain 100%, mode Extreme, inertia and friction off, damper 0%, spring auto. T300/T500: master gain 60%, constant 100%, damper 0%, 900° (Brian Koponen's alternative is in our T300 settings).
- Asetek (RaceHub): import the iRacing class preset (GT, formula, oval or dirt) and save it to the wheelbase.
TrueForce, FullForce and 360 Hz
- Wheel LFE sliders control Logitech TRUEFORCE and Fanatec FullForce vibration cues such as engine, gear changes, kerbs and wheel slip. Lower them if they mask the steering feel.
- 360 Hz force feedback: iRacing can send force feedback at 360 Hz on supported bases. MOZA enables it with recent firmware and Pit House; Asetek makes it optional in RaceHub.
- Buzzing after enabling 360 Hz (MOZA): set
enableFFB360HzInterpolated=0in app.ini (Documents/iRacing) with iRacing closed, or lower Wheel LFE.
Fixing common iRacing FFB problems
| Problem | Fix |
|---|---|
| Wheel goes flat or "dead" in fast corners (clipping) | Raise the Strength number (makes forces lighter) or press Auto again |
| Wheel far too heavy | Raise Strength; check Wheel Force matches your base, not higher |
| Wheel too light or vague | Lower Strength; on gear wheels turn Linear Mode off and add a little Min Force |
| Wheel oscillates on straights or in the pits | Turn on Reduce Force When Parked; add a little damping in the wheel software |
| Harsh jolts over kerbs and walls | Add Smoothing (25 to 50%) on gear or belt wheels |
| Different cars feel very different | Use Auto per car; lower Intensity to keep heavy cars heavier |

FAQ
What strength should I set my FFB at in iRacing?
Set Wheel Force to your base's rated torque, drive a few laps and press Auto. Then raise the Strength number if the wheel is too heavy or lower it if it is too light. In iRacing a higher Strength number means lighter forces.
What does iRacing FFB Strength mean?
It is the car steering force, in Nm, that maps to your wheel's maximum. If Strength is 10, any car force above 10 Nm clips. A higher number gives a lighter wheel with less clipping.
Should I use Linear Mode in iRacing?
Yes on direct drive. No on gear-driven Logitech wheels like the G29 and G923, where non-linear mode boosts small forces they would otherwise miss. (Brian Koponen's G29 guide uses linear on with 12% min force instead; see our G29 settings.)
What are the best iRacing FFB settings for a CSL DD?
Wheel Force 5 Nm (8 Nm with the Boost Kit), Strength around 8.5 to start, Linear Mode on, Min Force, Damping and Smoothing 0%, with SEN Auto and FF 100 on the base.
What are the best iRacing FFB settings for a MOZA R5?
Wheel Force 5.5 Nm, Strength Auto with intensity 100%, Linear Mode on, Min Force, Damping and Smoothing 0%, and wheel spring and damper 0% in Pit House. MOZA's own sheet differs (fixed 60 Nm strength, damper 35%); see our MOZA R5 settings and MOZA R9 settings.
Should I use Wheel Force Auto?
It can work, but it sometimes overestimates your base's torque. Typing in the rated torque is more predictable.
