Wilwood Rotor-GT48 SPC-37-LH 13.06 x 1.25 - 12 on 8.75in

Wilwood's GT 48 rotor is built with a proprietary iron alloy, a formulation derived from military-spec rotor technology. This material is chosen for its exceptional resistance to extreme temperatures, helping to prevent distortion, warping, cracking, and wear under heavy use. The rotor features Wilwood's GT Series asymmetrical face slot pattern, designed to help clear dust and gas, and is individually dynamically balanced for smooth, vibration-free performance.

This rotor is intended for applications demanding high cooling capacity and long service life, particularly in short track and road course racing environments. The 13.06-inch diameter and 1.25-inch thickness, combined with the curved vane design, contribute to its ability to handle intense braking conditions. You can expect a solid option for serious track use where consistent braking is critical.
