So, the 9.5" is ET22 and the 10.5" is ET27? If I can find some wheel templates, I can confirm that mine will fit.
I can't use any spacers, as my track wheels/tires (275/35) already rub (hoping new control arms and a good alignment will sort that out) and my street wheels (running 265/35) just barely clear.
I have been told directly from APEX, that all ARC-8 18" wheels with the M3 fitment fit over all brakes except Brembo 380mm.
Apex also tells people that 275/35 tires, on 18" ET25 wheels won't rub on our cars. I know rubbing is far different from caliper clearance, but I'm just not going to assume that Apex had this
BBK (which is still somewhat rare) in mind, back when they made that statement to you about the ARC-8.
