Wilwood UL-32 Ultra-Light Directional Vane Rotors for Racing Cars

Wilwood UL-32 Ultra-Light Directional Vane Rotors for Racing Cars Optimize braking performance with the Wilwood UL-32 Ultra-Light directional vane rotors — engineered for racers who demand rapid heat dissipation, reduced rotating mass, and a consistent pedal feel under extreme conditions. Key Features Ultra‑light directional vane design increases airflow through the rotor core to accelerate cooling on dirt tracks and high‑load pavement runs. Premium long‑grain carbon iron casting delivers extended wear life, superior thermal stability, and enhanced resistance to warping under repeated heavy braking. Production machined surfaces ensure precise thickness, flatness, and reliable rotor runout for repeatable brake bite and reduced pad wear. Low rotating mass is optimized for rear‑axle service and hard‑braking scenarios, improving vehicle responsiveness and reducing unsprung weight. Performance Benefits The UL‑32 rotor blends durable metallurgy with directional vane geometry to maintain cooler operating temperatures and consistent friction characteristics lap after lap. Drivers gain improved pedal modulation, reduced fade, and longer component life — critical advantages in sportsman racing classes. Application & Fitment Fitment: Designed for many sportsman‑level race vehicles and rear‑axle installations. Verify vehicle‑specific fitment and rotor thickness clearance before purchase. Ideal when you need a lightweight, track‑focused upgrade without compromising durability.
