Wilwood 160-15876-B GT Curved Vane Disc Brake Rotor Bedded - 48 Spec-37

The Wilwood 160-15876-B GT 48 Curved Vane Spec-37 disc brake rotor is engineered for serious motorsports applications demanding uncompromising stopping power and thermal durability. Cast from a proprietary iron alloy derived from Wilwood's extreme-duty military specification rotor technology, this rotor delivers exceptional resistance to distortion, warping, cracking, and wear—even under sustained high-heat conditions.

Key Features:

• Proprietary Spec-37 iron alloy formulation developed from military-grade rotor technology for maximum thermal stability
• 48 curved vane internal venting design maximizes airflow and heat dissipation for extended fade-free braking performance
• GT Series asymmetrical face slot pattern promotes consistent pad bite and progressive, predictable brake feel
• Individually dynamic balanced for smooth, vibration-free operation at any speed
• Bedded finish (denoted by the -B suffix) provides a pre-conditioned friction surface for optimized initial pad seating
• Engineered for short track and road course competition where maximum cooling capacity and long service life are critical

The GT 48 Curved Vane Spec-37 rotor represents Wilwood's commitment to race-proven brake technology, offering the highest cooling capacity and longest service life in its class for extreme braking environments. It is an ideal choice for competitive motorsports builds where consistent, high-performance braking is non-negotiable.
