For this purpose, the following measures have proven to be extremely helpful:
•
Place driver’s compensation weight on the driver’s seat
•
Set air pressure to 2.0 bar (29 psi)
•
Fill the tank with 50 % of the fuel quantity necessary for the race/practice
The following work order is recommended when performing a complete vehicle
alignment:
1.
Unhook the anti-roll bars
2.
Preset vehicle height
3.
Rear axle: set the camber first, then the toe
4.
Front axle: set the camber first, then the toe
5.
Set vehicle height and wheel loads
6.
Wheel loads are set by changing the vehicle height; you should try to reach the
lowest possible wheel load deviation per axle (left to right)
7.
Hook up the anti-roll bars without tension
