Thanks for the pics, I know what you mean, but it wont rub. There is people running 325's!!!! without any rubbing and no fender mod. Here is the link: http://www.m3post.com/forums/showthr...&highlight=325
Another member SHADY1 is running 360 wheels with 305 rears and H&R springs with no problems either. http://www.m3post.com/forums/showthread.php?t=163475
Obiously, there more a car is dropped, the less withd space it will have, even so, many dropped M3's run 305/25/20 with no problems.
I assume you ask this questions because you are interested in buying the tires, not just to troll, right?
BTW, these tires were for a set of 360 wheels that was canceled a while back. Therefore, Im selling them at a discount price.
