No they won't fit.
The PCD on Porsche 911 /993 is 5 x 130mm
whereas on the A4's it's 5 x 112mm
(PS - i know a bloke who fitted Replica Porsche Alloys with the 5 x 112mm fitment - this is what you've probably seen)
IMHO - it looks silly - buy a set of RS6 replicas - 18's - awesome.....
Audi Wheels for Audi Cars (again IMHO)
