I have been considering putting a supercharger on my 2012 e93 M3 and am concerned that my competition wheels with 265/35/19 tires in the rear will not be sufficient rubber. I'm assuming that if I want to run 305s in the rear and 285s in the front, I'll have to widen the front fenders. I really don't want to go the wide body kit route because all of the ones that I can afford are fiber glass, I can't roll the fenders because they're plastic and I don't want to take the fender liner out because my car isn't driven solely on the track. Of course, there's the option of not super charging the car but that would be the reasonable thing to do and if I was reasonable, then I would be driving a Prius and not posting this thread... I'm wondering if anyone knows of another option, whereby I can modify my front fenders to accommodate a much larger tire. Appreciate the feedback in advance.
