I currently have the ac schnitzer front and rear bumper on a 01 x5. I was debating whether i should get the oem aero kit with the current setup or do the 2004 front end conversion with the aero kit. Any advice is greatly appreciated.

ac schnitzer bumper (front and rear)
ac schntizer exhaust
two tone angel eyes
painted side trim
custom audio/video (mostly alpine and mbquart)
