Wheel-alignment corrections

Rear axle: The kinematic toe-in is not adjustable. Camber and toe can be adjusted via eccentrics.

Front axle: The caster is not adjustable on standard vehicles. In the event of repairs, a caster adjustment facility can be installed if necessary (as with the Boxster).

The camber is adjusted by moving the spring strut transversely. For this purpose, loosen the three fastening nuts of the spring-strut mount.

After adjusting the toe, the lock nuts on the track rods must be tightened to the prescribed tightening torque of 50 N.m (37 ftlb.).

The steering angle sensor must be calibrated if the previous wheel alignment values for vehicles with PSM (Porsche Stability Management) were changed! The steering angle sensor actual value must be checked after a suspension alignment which resulted in no changes being made to the wheel alignment values. 

The Porsche System Tester 2 is necessary to calibrate the steering angle sensor and to check the steering angle sensor actual value.
