StopTech Front 12.9" 328x28mm ST40 Trophy Big Brake Kit; Slotted Rotors, No Coating; 2-Piece Rotor; Pad Shape D609

They include forged, lightweight StopTech® STR calipers, floating, slotted AeroRotors, stainless steel brake lines, and race engineered caliper brackets. Easily identifiable by their unique shape and finish, StopTech® Trophy Big Brake Kit® components feature a MIL-spec hard-anodizing on the Trophy STR calipers and AeroHats® that is impervious to color change or fading at extreme race temperatures.
StopTech® Trophy Kits feature ultra-high performance STR lightweight forged calipers in six-piston, four-piston or two-piston configurations. Based on the highly praised StopTech® ST-60, ST-40, and ST-22 calipers, STR calipers feature the same metallurgy and design, but are engineered to provide up to a 20-percent reduction in weight without sacrificing stiffness or performance.
There are two types of StopTech® Trophy Big Brake Kits® available - one for the track and the other for the street.

Any StopTech® Brake Kit can be ordered as a Trophy Race or Trophy Sport(street) kit simply by specifying it on your order.

Differences Between Track and Street Kits

StopTech® Trophy Race Big Brake Kits®
Designed specifically for motorsports competition and dedicated track cars. Unique to the Trophy Race Big Brake System is full-floating mounting hardware, which eliminates pad knock-back, and the elimination of the dust boots in the caliper. Together, these technologies optimize the brake system to provide improved performance and consistent pedal feedback under the unique combination of hard cornering and braking found on the track. Trophy Race Big Brake Kits are the ultimate in racing performance, with numerous wins and championships in World Challenge, Grand-Am, NASA and SCCA racing.

StopTech® Trophy Sport Big Brake Kits®
Intended for ultra-high performance street use. They are designed for street driven production vehicles. The Trophy Sport Big Brake Kits use the same STR calipers, AeroRotors® and AeroHats® found in the full-race Trophy Kits, but add silicone dust boots for extended service intervals and anti-rattle rotor mounting hardware for quieter operation. They also include StopTech® Sport Brake Pads for high performance street and occasional track use. Trophy Sport Big Brake Kits are the ultimate street braking system.
