1. Bore out center bore from 72.4 to 74.1mm (or get appropriate centering rings if available for Meisters).
2. Fronts need a 20-25mm hubcentric 74.1mm spacer. Rear offsets are OK. You may need a 5mm spacer if it does not clear the strut housing. 275 tires on a 11" wheel is a stretch so fender should be fine. Roll if necessary.
I'm not 100% sure, but I think they're "replica" rims. one of them is cracked, too. it's either the poor quality, or the potholes around here, or maybe both. that's the reason I'm going back to OEM. if you find a new set of real M3 wheels and want to sell your OEMs, keep me in mind. I don't want to risk ripping you off on a trade, though.
