Transmission
Gearbox: T60 LFL (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.
Differential
Values computed for your car and kept within the sliders of your differential (a Clutch 65 if none is declared).
Differential: Clutch 65 (declared).
Stability first: the rear must never let go before the front. Preload keeps the inner wheel from spinning over a bump at the throttle you hold through a typical corner (computed from aero and tyre drag) and keeps the lock smooth between throttle and lift-off. Acceleration lock adds only what is still needed so the inner wheel doesn't spin up to 60 % of your lateral grip: on a rear-wheel drive car, more would push the rear out (in-game hint). Coast lock is half the acceleration lock (1.5-way), gentle so the car doesn't rotate when slowing down.
