A few things:
Sam: I really like what you did with the m3 ~ those red wheels and red mirrors really tie in well together and pop nicely. My only suggestion is now your red tails might be a bit too much and to smoke them ever so slightly. Just my 2 cents. Now you got me thinking yellow mirrors and yellow wheels!
What size are you front and rear tires? I think you have one of the nicest stances here for a E90 m3!
This is my setup right now, I'm planning to go a bit lower for a more "raked" look but the front lip is already so low I'm afraid to scratch it.
