I am looking at purchasing the OEM Aerodynamic body kit from tischer. Has anyone purchased this kit already and has picture they can post. Specifically I would like to know the running board type aluminum or black? And if I can fit 20" wheels with the kit. I have seen X5's on this forum with the aluminum running boards and the body kit, but the description says they are incompatible with the fender flares and 20" wheels. Any pictures would be greatly appreciated.
