I was wondering if anyone has the rennen body parts from www.rennentuning.com, not the kerscher parts (rennen must be a cheap knock off of kerscher). I am wondering if the rennen body parts are a good product and will fit on my 2002 Audi perfectly or is it just a peice of crap.

 

No aftermarket parts will ever fit perfectly. There will always be the need for tweaking and adjusting - some parts more than others. The cheaper the materilas used, the worse these adjustments will look after all is done.
