Rotor Size: 328mm (12.91") x 28mm (1.1"). Rotor Construction: 2-Piece. Rotor Style: Drilled. Rotor Coating: Zinc Plate. Rotor Type: Vented. Caliper Type: 4-Piston. Caliper Construction: Fixed. Caliper Series: STR-40. They feature fully forged calipers with patented stiffening bridges, patented 2-piece AeroRotors for optimized cooling.
Benefits:
- Slots create an escape route for debris, dust, gases, and water
- Slots reduce stopping distances in wet weather
- Slots clean and de-glaze pad surface for optimum pad coefficient of friction
- Slots help to increase pad bite and improve air circulation
- Vented type of rotors offer much faster heat dissipation
- Multi-piston calipers provide clamping force on both sides of the rotor at the same time and uniformly transfer braking force to the brake pads
- Caliper pistons are hollow to save weight
- Aluminum caliper body allows for exceptional light weight (up to 40% of weight savings) and ensures superior corrosion resistance
- Caliper heat-resistant coating prevent cracking and fading
- Fixed calipers create friction from the brake pads on both sides of the rotor at minimum time interval
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 brake 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 Street Performance brake pads for high performance street and occasional track use. They are the ultimate street braking system.
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.
StopTech has been awarded the highly coveted TíœV approval on several big brake kits. StopTech kits successfully passed TíœV's demanding series of tests that range from performance and durability, to proper fitment and ease of installation. Although TíœV certification is not required in all countries, TíœV approval demonstrates that StopTech's Balanced Brake Upgrades meet the rigorous standards set by this respected German Agency. StopTech Big Brake Kits have been awarded a Teilgutachten. The complete kit is certified to run on a particular application, so customers do not need to pay for further testing with the TíœV agency.
