are the a4 and the s4 the same bodies with different motors, for example if im looking for a lip spoiler for my s4 will ones for the a4 work??? same with bumpers and so on, are they interchangable??

secondly, im lookin for a new rs4 bumper set or a lip kit for my 2000 s4, what are some good companies that make body parts for these?

 

nobody has any clue??? come on............

 

yeah i already thought of the sponsors section...i dont think that royal purple sells body parts. the closest any of them come is absolute motoring but they still dont have body parts. and so my question of a4 body parts being interchangable still stands.

 

Yes, they are the same platform with different engines/brakes and some suspension tweaks like stiffer spring rates on the S4. The body trim stuff is interchangeable.
