StopTech 14+ BMW M3/M4 (F8X) Rear Big Brake Kit ST-40 Trophy Calipers 380x32mm Rotors
For ultimate track racing performance, StopTech offers Trophy Race Big Brake Kits, with naturally anodized lightweight components designed to survive the rigors of racing. Trophy Kits feature fully forged, lightweight STR calipers, 2-piece AeroRotors, braided stainless steel lines, mounting brackets, and hardware. The MAX Float hardware allows for the greatest amount of float between the hat and rotor. These Trophy Race Kits are used on many of the top competitors in the SCCA Pro Pirelli World Challenge Championship as well as in Grand-Am and other race series.
Ultimate street performance is obtained with a StopTech Trophy Sport Big Brake Kit. The Trophy Sport Big Brake Kits are designed for street driven production vehicles and use the same STR calipers, AeroRotors and AeroHats as the Trophy Race Big Brake Kits, but add silicone dust boots to extend service intervals and anti- rattle rotor mounting hardware for quieter street operation. Trophy Sport Kits also include StopTech Sport brake pads for high performance street and occasional track use. They are the ultimate street braking system.
Stiffer calipers offer:
Better pedal feel under extreme braking conditions Faster braking response
Less pad taper
