The Wilwood GT 48 Curved Vane rotor is manufactured from a proprietary iron alloy developed to resist extreme temperatures and reduce distortion, warping, cracking, and wear. With an asymmetrical face slot pattern and individual dynamic balancing, the rotor delivers smooth braking with minimized vibration and improved cooling, making it well suited to repeated high-demand stopping on tracks and road-course environments.
