BMW E90 front camber adjustment
Can the front camber on an E90 be adjusted, and where?
As standard there is no actual camber adjustment at the front. The adjustment is done at the strut top mount: the pin is removed, the nuts are loosened and the strut tower is turned. In some cars there is a hex socket bolt instead of the pin, and the adjustment is made through it.
What should be checked before adjusting the camber?
Check that the front control arms, the shoulder shaft or the hub have no damage. If the camber is too negative and the fault is not in the adjustment, adjusting alone does not fix it. The adjustment works only to a limited extent, for example in a lowered car.
How are the camber values chosen, and can the angles be checked at home?
The factory tolerance range is wide, and the values are chosen from within it according to the tyre size. The difference between front and rear camber must be at least 1 degree. Camber can be checked with an angle gauge or a spirit level, while the other angles require a measuring device.
