Audi just told me the wheel arches on an s3 are more flared than the a3. So they reckon an s3 kit wont fit properly anywhere. You guys showed me that seems to be a lie, but i'ma little worried that the 09' facelift s3 rear bumper & valence is a dfferent shape to the 07 s3 rear bumper & valence. Do you think it will be fine? Or can i mix and match 09' and 07' rear bumpers and valences?
