Hey check it out guys, just picked these up for my wife's X5 and decided to throw them on just for fun. Surprisingly they fit the m3. Well it does rub but it looks so good, I might just run them for a bit until I get the proper size tires for the X5.
specs:
21x9 et 23 front 255 30 21 pirelli
21x10.5 et 28 with a 10mm spacers rear 295 35 21
see it in person tomorrow at this meet
