Description

V8R StopTech STR kit is the ultimate in Miata brake performance! The STR-42 is the smallest and lightest 4-piston caliper developed from StopTech. Designed with high fluid pressures and forces in-mind, the STR-42 is the preferred option for blade type rotor systems. The stiff, lightweight STR-42 caliper provides a level of performance that did not exist before. It has a 30% increase in pad volume over traditional 4 piston lug mount kits.

Paired with our CAD designed and Finite Element Analysis (FEA) tested hats that weigh in just over 1lb, and are designed with cooling reliefs for greater thermal dissipation. 11.750″ rotors offer the largest thermal capacity available under 15″ wheels. Standard with our American made plain face directional rotors or optional PFC rotors.

Rear axle application we’ve worked directly with StopTech and engineered the lightweight STR-21 caliper over both the sport and non-sport rotor. The STR21 was designed to be used for the rear axle that requires less pad volume than the STR-22 and non-vented, solid rotors. This package can be implemented in smaller wheel diameters, typical of most front-wheel drive race cars. Even with its smaller size, the STR-21 maintains caliper stiffness and optimal pad wear to provide the best performance in its class.

Sold padless to allow your preferred pads. We carry a full line of pads from PFC to Hawk and can help advise a good pad compound for your needs.
