All i have is the stock sport suspension. I plan on doing an h&r and bilstien combo. I dont know if i will have to roll the fenders. They are 18x8.5 all around, with 225/40/zr18 pirelli pzero asimmetrico's.As for the exhaust, they are just BMW tips. I plan on going with a 100% stainless supersprint. I am debating on dtm's or straight. I am getting rid of the spoiler, and plan to get a BMW motorsports intl. wing. I dont want to use the extensions though.
