BMW Z3 camber and alignment angles: rear and front adjustment
Are eccentric bolts enough for adjusting Z3 rear camber?
Eccentric bolts alone may not be enough, because the adjustment range is small. The eccentric diameter of the E39 eccentric bolt is 33 mm and gives more adjustment range than the 28 mm bolt of the E34 M5.
How do you set the slotted plates for camber and toe adjustment?
The outer plate adjusts toe horizontally and the inner one adjusts camber vertically. Set the plates as straight as possible and the camber adjustment almost fully upward. Wheels set more upright can rub the rear wheel arches.
Does alignment have to be done after a ride height adjustment?
Yes. A change in ride height changes the wheel angles, so a four-wheel alignment should be done right after the change. Otherwise the tyres wear unevenly.
What values are the Z3 2.2 alignment angles set to?
Standard suspension, front: toe 0.30 degrees, camber -0.73 degrees, castor 3.80 degrees. Rear: toe 0.57 degrees, camber -2.33 degrees. Sport suspension, front: toe 0.30, camber -1.07, castor 3.93. Rear: toe 0.68, camber -2.83 degrees. The measurement is done with a full tank and extra weights (68 kg on the front seats, 14 kg in the boot).
