I know the 330i performance package isn’t available on the 330Ci, but he is the big question, can’t we just put the mods on ourselves. What does the performance package consist of? Im not interested in the suspension or wheels as I feel the 330Ci with sports package will have the same suspension, and the wheels are nothing special (although the look nice). Do you think we will be able to change headers, ecu, muffler, etc? Limme know what you think. Thanks!
