Wilwood Rotor-GT48 SPC-37-LH 12.72 x 1.25 - 8 on 7.62in

This listing is for a single Wilwood GT 48 curved vane brake rotor, measuring 12.72 inches in diameter and 1.25 inches thick. It features an 8-bolt mounting pattern on a 7.62-inch bolt circle and utilizes Wilwood's Spec-37 iron alloy, a formulation derived from military-grade rotor technology. This material is specifically chosen for its exceptional resistance to high temperatures, preventing distortion, warping, cracking, and wear under extreme braking conditions.

The rotor is designed with Wilwood's GT Series asymmetrical face slot pattern, which helps to clear dust and gas, ensuring consistent braking performance. Each rotor is also dynamically balanced to provide a smooth, vibration-free experience at any speed. This rotor offers high cooling capacity and a long service life, making it suitable for demanding applications like short track and road course racing where extreme braking is common.
