Description
Part #: 83.841.4300.R1
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 StopTechSTR calipers, floating, slotted AeroRotors, stainless steel brake lines, and race engineered caliper brackets.
