If you're planning on bastardizing your BMW with some gold 100spoke ghetto wheels, you might as well get some neon lighting to go underneath the car, as well as, a 5" exhaust system(need one of those if you're gonna go ghetto!), tinted windows ALL around, gotta get at least 4 subs(everyone within 200 ft. should be able to hear the bass from your car--it's gotta be cool, right?), and you definitely need a 6" wing too!
