Been thinking of when I adapted the Z4 with a set of Z4 M rotors and 135i calipers with a 5mm spacer and they bolted right up, does anybody know if adding such a spacer and moving the caliper outward would be enough to fit the 1M rotors ? Didn't know if this was done before and seems easy enough. It be nice to fill up the wheel with more rotor.
