Transmission

Gear 5 1
Gear 6 0.8

Gearbox: T50S (declared by you, in the form or when sharing).

Your gearbox ratios are kept and only the final drive is adjusted, so the last gear reaches top speed at the top of the power band. This is not an optimal gearing: in our simulations on the game's tracks, no other rule does demonstrably better, whatever the discipline. Not validated in game.

Gearbox recalculated on 2026-09-25: corner exit speed and target top speed are no longer used, and the final drive stays within the game's slider range. The proposed ratios, and the differential that depends on them, may differ from those shown before.

These ratios can only be adjusted in game with a Racing or higher gearbox upgrade (GBT3 and up). That part's final drive factor is not applied: the tool doesn't know which one is installed.

Differential

Accel lock 0.62
Decel lock 0.3
Preload 100Nm

Physics-based target value, not capped to the real max achievable in-game (which depends on your installed differential). Get as close as you can without forcing past the slider's limit.

Differential: Clutch [P] (declared).

Values brought within the slider range of your differential (Clutch [P]), ranges with every tuning step purchased.

Tyre compound not declared: rear lock computed for a Racing compound. With a less grippy compound (Street, Sport), the minimum is lower. Declare your compound in the form.

Acceleration lock (rear): the minimum so the inner wheel does not spin alone out of corners. You can raise it without losing traction: the car then slides more progressively, but it understeers more on throttle, especially if you go much higher (in-game hint). Approximate calculation, about ±0.1.

Coast lock, preload and front axle: reference values (tuning choices, not a calculation from your car). At the front: little lock and no coast lock (1-way), so the car turns in well. Not validated in game.
