If I am not mistaken you can fit four of the front wheels, but the rears won't fit, though I don't why you would want to willingly get M3 wheels when there are so many other way better looking wheels around.
what are the specs of the M3's rear rim? cus i know Arbee had a set of Individual rims exact like mine from my E90 which was 255 width at the rear and 225 at the front and his had no rubbing or touching and stuff.
I've seen an e36 sedan with 18"inch e46 M3 rims narrows and wides and that car was running 225/40 in front and 235/40 tyres at the rear.... but it wasn't lowered
