The Wilwood GT/GTB 72 Spec-37 curved-vane rotor family is cast from a proprietary iron alloy to resist distortion, warping, cracking, and wear under extreme heat. GT rotors pair an asymmetrical face slot pattern with individual dynamic balancing for smooth braking; GTB versions add a black e-coat for added corrosion resistance where environmental protection is a concern.
