i dont really have a good opinion on it being i am a racer first and foremost. if it can be done without sacrificing much performance then its ok with me. but some cars (like the z3 coupe posted earlier with the lip scraping the ground in a driveway) have taken it a bit overboard. it's not that it doesnt look nice. it does, but as stated i race my car every chance i get at the tracks around here. my front bumper is already damaged from bottoming it out repeatedly on a steep incline at one of the tracks. and that was on stock suspension. i'm currently building up some parts to go with my 1 year used dgr's so we'll see.
your car will never be like my car, after all you have common sense......
