Wilwood Rotor-GT60 SPC-37-RH 15.00 x 1.25 - 12 on 10.25in

Wilwood's GT 60 Curved Vane Spec-37 rotors start with a proprietary iron alloy, a material developed to handle extreme temperatures without distorting, warping, cracking, or wearing out. This alloy draws from technology used in Wilwood's heavy-duty military spec rotors, giving you a solid foundation for serious braking performance. The 15-inch diameter and 1.25-inch thickness are substantial, designed for applications where heat management is critical.

These rotors feature Wilwood's GT Series asymmetrical face slot pattern, which helps clear dust and gas away from the braking surface for consistent stopping power. Each rotor is also dynamically balanced to ensure a smooth, vibration-free experience, even at high speeds. This combination of advanced materials and thoughtful design makes them ideal for short track and road course racing, offering excellent cooling and a long service life under demanding conditions.
