Wilwood 160-15873-B GT Curved Vane Disc Brake Rotor - Spec-37

The Wilwood 160-15873-B GT 72 Curved Vane Spec-37 disc brake rotor is engineered for performance-demanding applications where heat resistance and long-term durability are critical. Each rotor is cast from Wilwood's proprietary iron alloy — a formulation derived from the same material technology used in their extreme-duty military-spec rotors — providing exceptional resistance to distortion, warping, cracking, and accelerated wear even under sustained high-temperature braking conditions.

Key Features:

• Proprietary Spec-37 Iron Alloy: High-performance iron compound developed for maximum thermal stability and structural integrity at extreme temperatures
• GT 72 Curved Vane Ventilation: 72 curved internal vanes promote aggressive airflow through the rotor for rapid, consistent heat dissipation
• Asymmetrical GT Series Face Slot Pattern: Wilwood's proven slot geometry continuously sweeps brake pad surfaces to remove gas, dust, and debris, maintaining consistent bite and pad contact
• Individual Dynamic Balancing: Every rotor is individually balanced at the factory to eliminate vibration and ensure the smoothest possible braking feel
• Military-Derived Alloy Technology: Material formulation shares heritage with Wilwood's extreme-duty military-specification rotor program
• Black Anodized Finish (-B Suffix): Corrosion-resistant black finish for enhanced appearance and surface protection

The Wilwood GT Spec-37 rotor series represents a direct application of motorsport and defense-grade metallurgy in a high-performance street and track brake rotor. The combination of curved vane ventilation, precision slot patterning, and individual dynamic balancing delivers fade-resistant, vibration-free stopping power across a wide range of demanding conditions.
