Digging up this thread. I fitted 12mm spacers all round on my Z4M which has (as far as I know) stock suspension/wheels/tyre sizes. Getting rubbing on full lock up front now, which (according to what I have read in this thread and elsewhere) is unusual.
It may be that my alignment is off, but I don't think the camber can be that far out with stock suspension. Anyone else had this problem?
