Wilwood GT 48 Curved Vane 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. Every Spec 37 rotor is precision machined to less than .001" run-out, flatness, and parallelism. Combined with proven GT Series asymmetrical face slot pattern and individual dynamic balancing, you are assured the smoothest, 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.
GT48 Rotors are designed to mount to a separate bell and are available in different mounting PCD's. Pre bedded versions are also available which have been dyno bedded and ready to race on thier first warm up cycle. This is ideal where it is not possible to bed the rotors in on track. GT48 rotors are handed so please select one of each side for a vehicle pair.
