How to read this table: Each row always shows that sim's own researched peak Nm — independent of the Sim Output Max slider above. The slider sets the main chart only. To update a row here to a specific car, click the row to select that sim, then pick the car category.
Click any row to select that simulator. The feel rating reflects dynamic range coverage quality at the selected mode and gain.
Note on rF2 / LMU: These sims use a per-car NominalMaxSteeringTorque (NMST) calibration model. Users match "Steering Torque Capability" to their WB Nm for 1:1 reproduction. NMST values (11–22 Nm) are much lower than iRacing's raw MaxForceNm, explaining why smaller bases feel excellent on rF2/LMU.
Note on GT7: Calibrated for the Fanatec GT DD Pro (8 Nm) originally; Spec III/FullForce raised peaks slightly. Forces are intentionally modest vs PC sims — designed for console accessibility.
Note on ACC: Pure steering-rack physics — no canned effects. Every Nm comes from SAT, pneumatic trail, and mechanical trail simulation. All cars have power steering; force differences are purely from downforce and speed tier.
Modes Reference
Clip mode — gain at 100%: forces below wheel base max are preserved exactly, forces above all feel identical.
Scale mode — gain reduced: no clipping, but every force is proportionally quieter. Fine road texture may fall below perception threshold.
