Gearbox: top speed you can actually use
The useful top speed is the speed reached at the rev limiter in the last gear, limited by aerodynamic drag. There is no point gearing for a speed the car cannot reach, so the final drive is adjusted until the last gear ends exactly there. A gearbox that tops out too early wastes speed on the straights, and one that is too long leaves you slow out of corners.
Suspension: stiffer than touge, flatter body
Stiffer springs and anti-roll bars reduce body roll, which keeps the tyre contact patch flat on the road and the load stable. Do not go as stiff as a track build on a street car: you still need the tyres to follow the surface. Tune the slow dampers first, because they control the car under steering, braking and throttle.
Differential: lock sized to your grip
The right lock depends on the real torque, the grip of the tyres and the load transfer, not on a generic number. A low-torque, high-grip car needs little lock, and too much makes the car push wide or step out on exit. Preload keeps the inside wheel from spinning over a bump at the throttle you hold through a typical corner.
Alignment and brakes
Camber, toe and caster are adapted to grip driving and to the drivetrain. The brake bias comes from the weight distribution and the load transfer under maximum braking, so a front-heavy car gets more front bias.
Practical tips
-
01
Enter the real tyre grip index shown in the game, it changes the differential and the alignment.
-
02
Change one setting at a time and keep the same test corner.
-
03
If the car understeers, check the front anti-roll bar and the camber before the springs.
FAQ
How is a grip tune different from touge?
It is stiffer and flatter, with a gearbox aimed at the usable top speed rather than at hairpins.
Why does the final drive matter?
It decides where the last gear tops out. It is set so the last gear reaches the top speed the car can really reach against aerodynamic drag.
