Wilwood 160-15872-B GT Curved Vane Disc Brake Rotor - 48 Spec-37

The Wilwood 160-15872-B GT 48 Curved Vane Spec-37 disc brake rotor is engineered for serious performance applications where heat, stress, and precision matter most. Cast from a proprietary iron alloy developed by Wilwood's engineering team, this rotor delivers exceptional resistance against distortion, warping, cracking, and wear even under the most extreme braking conditions.

The alloy formulation draws directly from technology and materials developed for Wilwood's extreme-duty military-spec rotor production — bringing proven durability to high-performance motorsport applications. Combined with Wilwood's GT Series asymmetrical face slot pattern, the rotor promotes consistent pad bite, improved heat dissipation, and reduced brake fade during hard use.

Key Features:

• Proprietary Spec-37 Iron Alloy — Engineered for maximum resistance to heat-induced distortion, warping, and cracking
• 48 Curved Vanes — High-capacity vented design maximizes airflow and cooling efficiency for sustained performance
• GT Series Asymmetrical Face Slot Pattern — Promotes pad deglazing, improved bite, and consistent friction performance
• Individual Dynamic Balancing — Each rotor is dynamically balanced for smooth, vibration-free operation at any speed
• Military-Derived Alloy Technology — Material science roots in Wilwood's extreme-duty military rotor manufacturing
• Designed for short track and road course competition where extreme braking demand is constant
• Delivers the highest cooling capacity and longest service life in its class

The Wilwood 160-15872-B is the ideal rotor choice for competitive drivers who demand race-proven reliability and consistent stopping power lap after lap.
