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

Close ratios: every gear is recalculated so 2nd gear exits your slowest corner at the bottom of the powerband, then the gears tighten up to top speed, each within the in-game slider.

These ratios can only be adjusted in game with a Racing or higher gearbox upgrade (GBT3 and up).

02

Differential

Accel lock 0.26
Decel lock 0.13
Preload 102Nm

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.
