Big Reds? You mean the big Porsche Brembos used on the 930's?
Which kit is this????
So far I have only located 3 Kits to retrofit S4's.
1. Audi-Hoppen Kit, a huge 2 Pot 4pc. pad as used on the S6+.
2. AP 6 Pot Kit.
3. KVR 4 Pot AP kit.
Anybody know of any others?
Stillen makes a kit for A4's but I do not think it works on an S4
I would prefer Brembo Calipers. When I put them on my Mercedes 190 2.3 16V
it made a huge-huge difference in feel and stopping difference.
Any Brembo kits out there for S4's???????
