Wilwood HD 48 Curved Vane Spec-37 Rotors 355mm High-Temp Alloy

Wilwood HD 48 Curved Vane Spec-37 Rotors — 355mm High-Temp Alloy Optimized for extreme heat , the Wilwood HD 48 Curved Vane Spec-37 rotors are engineered from a proprietary high-temperature iron alloy to deliver superior resistance to distortion, warping, cracking, and wear. Built from materials and processes derived from Wilwood's military-grade rotor programs, these rotors bring heavy-duty durability to performance and commercial applications. Size: 355mm diameter for increased thermal capacity and braking leverage Design: Curved vane ventilation improves airflow and heat dissipation under sustained braking Material: Spec-37 high-temp alloy formulated for maximum structural integrity at elevated temperatures Finish: Precision machined pad contact faces — smooth, without slots — for consistent pad engagement and predictable bite Application: Ideal for track, tow, heavy-use street, and commercial vehicles requiring robust thermal stability Choose Wilwood HD 48 Spec-37 rotors when you need long service life and reliable performance in the most demanding braking environments. Backed by racing- and military-proven metallurgy, these rotors reduce the risk of failure under extreme duty while providing consistent pedal feel and fade resistance.
