[s-cars] AP 4 piston calipers for URS

[RCaro900SS at aol.com]

I am running 6 piston AP Racing calipers with 343mm AP rotors on aluminum 
hats. They required S6+ lower strut assemblies. They fit under Ronal SL's, OZ 
Superleggeras, and SSR Competitions. These are all 17 inch wheels. 

I have done some research for my daughter's A4 and found that the 4 piston AP 
Racing calipers are substantially slimmer than the Brembo, and Stoptech.
