Stoptech 07-08 Audi RS4 V8 4.2L Trophy Sport Rear BBK ST40 Caliper / 2pc Slotted 355x32mm Rotor

The ultimate street braking system; with naturally anodized lightweight components adapted from our racing program. They use the same STR calipers; AeroRotors(R) and AeroHats(R) as the Trophy Race BBKs; but add silicone dust boots to extend service intervals and anti-rattle rotor mounting hardware for quieter street operation. They also include StopTech(R) Street Performance brake pads for high performance street and occasional track use; and StopTech Stainless Steel Lines. Any StopTech BBK can be ordered as a Trophy Sport Kit by specifying it on the order form. They include forged; lightweight StopTech STR calipers; floating; slotted AeroRotors; stainless steel brake lines; and race engineered caliper brackets. 2007 - 2008 Audi RS4
