Step 1 - Go out for a lap and evaluate what is the condition of track (smooth, or bumpy) having this information, fully lower the ride height until the car’s floor hits the ground, then you will have to adjust the ride height until it doesn’t hit the ground anymore. Do not touch it again. If you may need to re-calibrate the hardness of springs and fast rebound dampers as necessary, including the camber angle.
Step 2 - Once you have the car height set, then putting the suspension bump stops in ZERO. Set the springs, as hard as possible considering that the rear axle is always softer. Go out and test on the track.
Step 3 - Then the sway bars, if you want the car to handle with a pointing front, set sway bars to hard as possible. The idea is to look for a balance by achieving a perfect curve approach while minimize front tire wear. Keep in mind that the sway bars keep the balance of the weight transfer between the wheels of the same axle.
Step 4 - The differential has 4 aspects that can modify the handling
A – Acceleration lock: It only acts when we step on the accelerator. A higher the percentage gives more power to the outer wheel to get the car to complete turn at the exit.
B - Deceleration lock: It only acts when the throttle is released. A higher percentage gives more lock to the inner wheel to facilitate cornering in the entry.
C- Preload: the differential preload parameter tells you how abrupt the differential will do the transition from one state to another (acceleration-deceleration)
Step 5 - Shock/Dampers compression and expansion notes:
The extension/rebound is always harder than the compression/bound.
The slow compression/bound and slow extension/rebound are always harder than the fast compression/bound and fast extension/rebound.
Setting high values of extension/rebound and compression/bound will give less grip, less tire wear and quick response to change of direction. Other hand, setting low values of extension/rebound and compression/bound will give more grip, more tire wear and a slow response to change of direction.
