Wilwood GT 72 Curved Vane Spec-37 Rotor 355mm High-Temp Alloy

Wilwood GT 72 Curved Vane Spec-37 Rotor — 355mm High-Temp Alloy Built for extreme duty and repeatable stopping , the Wilwood GT 72 Curved Vane Spec-37 rotor (355mm) is machined from a proprietary high-temperature iron alloy to resist distortion, cracking, and accelerated wear under severe braking loads. Performance Highlights 355mm diameter — Ideal for high-performance road, track, and heavy-duty applications that demand increased swept area and thermal capacity. Spec-37 high-temp alloy — Derived from Wilwood’s military-grade metallurgy for superior thermal stability, reduced thermal cracking, and extended service life. Curved vane cooling — Aerodynamic vane geometry maximizes air flow through the rotor for faster heat dissipation and reduced brake fade during repeated stops. GT Series asymmetrical face slots — Optimizes pad bite, evacuates gases and debris, and maintains consistent friction across temperature ranges. Individually dynamically balanced — Minimizes runout and vibration for smooth pedal feel and improved component longevity. Why Choose the GT 72 Spec-37? This rotor pairs advanced metallurgy with proven vane design and precision balancing to deliver consistent, fade-resistant braking under extreme conditions. Perfect for motorsport, aggressive street use, towing, and heavy-duty applications where thermal endurance and reliability are critical. Durability, cooling, and consistent performance — the Wilwood GT 72 Spec-37 355mm rotor is engineered to keep you stopping reliably when it matters most.
