            I had always heard from the old school guys that it disrupts the airstream flowing over the car so the car behind them has more trouble streaming them.

                i have very lil knowledge about this topic but i fig id put my 2 cents in.


                DTM tips...not really, well in germany yes, here in fresno/clovis cali i have yet to ever see a e30 or any rwd german car with DTM tips the only cars i ever see with them are RICED out honda's, VW's, and toyota's. and at that most are held on by bailing wire or just the pipe itself...ask me how i know :D

                      True, but they actually look good on E30 M3's when the tips follow parallel with the rear bumper line.
