ProMatrix Front and Rear Rotor Kits offer measurable brake performance improvements to racers and enthusiasts using the OE factory brake calipers. Two piece aluminum hat and GT 72 & 32 Curved Vane Spec-37 assemblies are used to provide high temperature durability for the track and high-tech style for the street. Spec-37 rotors are manufactured from a proprietary iron alloy developed to withstand extreme temperatures with the highest possible degree of resistance against distortion, warping, cracking, and wear. The formulation for this alloy is a derivative of technology and materials that were significant in the development of the extreme duty military spec rotors that are manufactured by Wilwood.
ProMatrix replacement rotors offer increased performance over OE brake rotors. Whether fitted in a one piece or two piece construction, ProMatrix rotors are suited for drivers that use OE factory brake calipers with higher friction pads. ProMatrix rotors feature high temperature durability and a black e-coat for corrosion resistance during street driving. Two piece rotors are constructed with a lightweight aluminum hat for weight savings.
