Wilwood 160-11728 Features:

Wilwood GT 48 Series Curved Vane Spec-37 Dynamic lug mount 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 technology and materials that were significant in the development of the extreme-duty military spec rotors that are manufactured by Wilwood. Combined with the proven GT Series asymmetrical face slot pattern, individual dynamic balancing, and dynamic lug mounting, you're 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. They're available separately for the driver and passenger side.
