Nice Car Sootyvrs,
I have a similarly tight fit with my 16" winter alloys on my 120d msport. (smallest size alloy for the brake size) Don't be surprised if you have some deep scratches on your wheel insides after removing them, when stones get caught up on the inside against the caliper they have nowhere to go but to damage your alloys!! Its only the inside tho right
Would love an M135i, so very jealous!
