Wilwood Rotor-GT48 SPC-37-LH 12.88 x 1.25 - 12 on 8.75in

This is a Wilwood GT 48 curved vane brake rotor, measuring 12.88 inches in diameter and 1.25 inches thick. It's built from Wilwood's own Spec-37 iron alloy, a material developed to handle extreme heat without distorting, warping, or cracking. This alloy comes from technology used in military-spec rotors, so you know it's tough. The rotor features Wilwood's GT Series asymmetrical face slot pattern, which helps clear dust and gas for consistent braking performance. Each rotor is also dynamically balanced to ensure a smooth, vibration-free feel at any speed.

These rotors are designed for high-performance applications where cooling capacity and a long service life are critical, such as short track or road course racing. The curved vane design further aids in heat dissipation, keeping your brakes cooler under heavy use. If you're pushing your vehicle hard on the track or in demanding situations, these rotors offer a solid option for improved braking endurance.
