I'm not certain that they fit without actual fender rolling. I'm almost sure that both front and back are wider in RIM size and the offers are what cause issues.
Without a wide body and wide fenders I don't think it'll fit properly.
That tire size is definitely off too because my 335 is wearing 225/35/19 in the front and 255/30/19.
The M3 would likely be using a wider set-up which again would cause issues.
Double check with someone who has actually done this.
