Description

Wilwood Ultralite HD 16 curved vane brake rotors can handle the heat and keep you in the race. These Spec-37 rotors are machined 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 the technology and materials that were significant in the development of the extreme-duty military spec rotors manufactured by Wilwood. On the dirt or asphalt, Wilwood Ultralite HD 16 curved vane brake rotors are right at home. They're available separately for the left and right side of your vehicle.
