Just bought a new OEM m-sport rear bumper w/ LCI diffuser for my 2006 330i. Added to a short list of subtle mods to give it an aggressive OEM look:
-OEM silver 219M's - tires: F: 235/40 18's R: 265/35 18's
-OEM blacklines
-m3 rep spoiler
-black out grills
-BMS PBX
-OEM Euro airbox w/ K&N filter
-CF wrap
-ZHP shift knob
-M sport steering wheel
Next mod?... nothing! maybe buy an e30 and put money into that instead
