Kits in this competition group are configured for road racing on vehicles equipped with OE production based suspension in categories where brake system upgrades are permitted. Each component is selected application specific for performance and durability in sustained high heat competition. All kits include forged aluminum, fixed mount “ST” series calipers equipped with Thermlock® pistons to resist fade and extend service life by reducing the heat transfer into the calipers from the pads. GT series Spec 37 alloy rotors provide high cooling efficiency, thermal stability, and durability. Overall unsprung and rotating weight are minimized by mounting the rotors to the hubs or axle with forged aluminum hats. Kits also include high temperature race compound pads, stainless steel braided flexlines, caliper mounting brackets, and all premium grade hardware.
