Setting the wheel alignment, or “tracking”, affects vehicle manageability and grip. Wheel alignment is a standard procedure on serially-produced cars and is usually done only on the front side. All settings are being done according to parameters that exist for virtually every car model.
In a tuned car, camber angle leans towards the center of the vehicle (unlike that in a serially-produced one), the amount of positive caster is increased because it affects the overall grip, and so is the toe-out angle as it helps free up the car while entering a corner. The given parameters do not allow any inconsistencies because a car that achieves greater acceleration needs to be as direct as possible and “accept” what the wheel commands.
Simpler elements like bearing balls that are used in serially-produced cars do not allow maximum precision and are prone to micro-tolerances. For the purpose of tuning, they are being replaced with the so-called uniball ties that reduce the tolerance to zero. This way it’s possible to achieve greater precision on the forks, steering mechanism and control arms.
It goes without saying that the front suspension of a race car, as well as the rear suspension that also undergoes a process of tuning (although much less), need to be done precisely and in line with a well-prepared calculation.
