About Wilwood

Wilwood Engineering has been the American leader in aftermarket racing brakes since 1977. Forged aluminum calipers, two-piece slotted rotors, and master cylinders engineered for NASCAR, IndyCar, sprint cars, and street-legal big brake kits.

Wilwood GT 48 Curved Vane Spec-37 Brake Rotor - Left Hand

Enhance your vehicle's braking performance with the Wilwood GT 48 Curved Vane Spec-37 Brake Rotor, engineered for extreme conditions. Constructed from Wilwood's proprietary Spec-37 iron alloy, this rotor is built to withstand intense heat, resisting distortion, warping, and cracking. The alloy's formulation is based on technology used in high-performance military-spec rotors, ensuring exceptional longevity and reliability.

Advanced Features:

  • Material: High-grade Spec-37 iron alloy for superior thermal management.
  • Vane Design: Curved vanes and asymmetrical face slots promote maximum airflow and heat dissipation.
  • Dimensions: 12.19" diameter, 1.25" thickness.
  • Bolt Circle: 8 on 7.00" bolt circle.
  • Hand Orientation: Left Hand (LH) specific design.
  • Balancing: Precision dynamic balancing for smooth, vibration-free braking.
  • Cooling: Optimized for the highest cooling capacity in demanding applications.

The GT Series rotors incorporate a sophisticated asymmetrical face slot pattern and curved vanes, designed to effectively clear heat and debris from the pad surface. This leads to consistently smooth braking and extended rotor life, especially during aggressive driving on road courses or short tracks. Benefit from the highest cooling capacity and longest service life available for competitive braking. Get your Wilwood GT 48 rotors at GGCRACING today.
