Wilwood HD curved vane rotors are built for the extreme conditions of professional motorsports. The superior thermal stability and long life provide a great rotor for asphalt late models, modifieds, open wheel, and most other types of high heat competition applications. All rotors are cast from premium grade, long grain carbon iron for long wear, thermal stability, and resistance to distortion. Every HD rotor is fully detail machined to eliminate stress points and unnecessary weight away from the pad sweep face. The faces and O.D. are precision turned to less than .001" for flatness, parallelism, and run-out. Every rotor is then individually dynamic balanced to provide vibration free performance at any speed. These rotors provide the highest cooling capacity and longest service life for extreme braking short tracks and road course competition.

Wilwood's HD Curved Vane Spec-37 material 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. Every Spec 37 material rotor is precision machined to less than .001" run-out, flatness, and parallelism.
