Wilwood 160-8165-GTB GT Curved Vane Disc Brake Rotor - 48 Spec-37

The Wilwood GT 48 Curved Vane Spec-37 rotor is engineered for extreme braking conditions in road racing and short track competition. Manufactured from a proprietary iron alloy originally derived from military-spec rotor technology, this rotor delivers exceptional resistance to thermal distortion, warping, cracking, and wear under sustained high temperatures.

Key Features:

• Proprietary Spec-37 iron alloy formulation for extreme temperature resistance
• 48 curved vane design maximizes internal airflow and cooling capacity
• GT Series asymmetrical face slot pattern optimizes pad bite and gas evacuation
• Individually dynamically balanced for vibration-free performance at any speed
• Superior resistance to distortion, warping, and cracking under extreme loads
• Designed for short track oval and road course competition applications

The combination of advanced metallurgy, directional curved vane cooling, and precision slot pattern makes the GT 48 Spec-37 rotor ideal for racing applications that demand maximum thermal capacity and consistent performance lap after lap. Each rotor is individually balanced to ensure smooth operation throughout the entire speed range.
