Wheel alignment

BMW have a bulletin 33-01-98 about the eccentric bushing used in the rear suspension to facilitate toe set alignment on the rear of your Z3. For standard height suspension (does your car have modified, altered or sports suspension?) is toe set 30 minutes +/- 13 minute. camber - 1 degree 45 minutes +/- 30 minutes, your alignment spec sheet should have actual measurements on it before and after the alignment was carried out. Are any of the actual measurements out of specification?

Toe adjustment. Mine is lowered, which only makes worse the typical BMW camber issue. Toe-in adjustment will address the wear issue.
