well it only took about an hour and a half to install them well that what im guessing cuz i had not planned on installing any but the fed ex guy came while i was taking off my fog light bar (i cant turn them on anyways) to make room for the brake ducts and ram air to the fender(where my air filter is at) its amazine my car looks much better not that it dosent have positive camber. yay now im going to test it after my bmw meet and drive at 4
