i have 4 wheel disc brakes from wilwood, and they are alot lighter , out perform the stock brakes, they are 4 piston calipers, vs slider calipers, yes they are fine for the street,actually the stock brakes are quite good, however i glazed them , and turned them blue after 4 or 5 laps, so if you road race wilwood, if you plan to street , stock is the best way to go
