Wilwood 160-15875-B GT Curved Vane Disc Brake Rotor Bedded - 48 Spec-37

The Wilwood 160-15875-B GT 48 Curved Vane Spec-37 disc brake rotor is engineered for serious motorsports competition, delivering exceptional thermal management and structural durability under the most demanding braking conditions. Cast from a proprietary iron alloy derived from Wilwood's extreme-duty military-spec rotor technology, this rotor is purpose-built to resist distortion, warping, cracking, and accelerated wear even at extreme operating temperatures.

Key Features:

• Proprietary Spec-37 Iron Alloy: A high-performance iron formulation developed from military-grade rotor technology, offering superior resistance to heat-induced warping and cracking
• 48 Curved Vanes: Maximizes airflow through the rotor for exceptional cooling capacity and extended service life under repeated heavy braking
• GT Series Asymmetrical Face Slot Pattern: Reduces harmonics and promotes more consistent thermal distribution across the rotor face for smooth, fade-resistant braking
• Individual Dynamic Balancing: Every rotor is dynamically balanced at the factory to eliminate vibration at any speed
• Bedded Finish (-B): Factory pre-bedded surface treatment for optimized pad-to-rotor break-in right out of the box
• Precision Machined Faces: Faces and O.D. turned to tight tolerances for flatness, parallelism, and minimal runout

Designed for short track and road course competition, the GT 48 Curved Vane Spec-37 rotor delivers the highest cooling capacity and longest service life available in Wilwood's GT rotor lineup. It is an ideal upgrade for racers who demand consistent, vibration-free stopping power lap after lap.
