Transmission

Final drive 3.492
Gear 1 2.92
Gear 2 2.31
Gear 3 1.82
Gear 4 1.44
Gear 5 1.14
Gear 6 0.9

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.

Drag results recalculated on 2026-09-24: transmission efficiency and gear shift time are now taken into account. Times and suggested ratios may differ from what was shown before. Since your dyno capture is present, torque is also derived from the measured power (it drops by up to about 35% at high rpm).

Simulated shift time: 0.19 s, your gearbox's (and your clutch's, if declared when sharing). Drag results recalculated on 2026-09-25: this time used to be 0.5 s for every car.

Differential

Accel lock 1
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.
