Wilwood ULHP-32 Ultra-Light Rotors for Dirt Track Cars 355mm Straight Vane

Wilwood ULHP-32 Ultra-Light 355mm Straight Vane Rotors for Dirt Track Cars Brand: Wilwood — Model: ULHP-32 Ultra-Light Rotors (355mm) Engineered for dirt-track competition and demanding rear-axle duty, the Wilwood ULHP-32 delivers race-proven stopping power with significantly reduced rotating mass. These 355mm straight vane rotors combine lightweight design, high thermal capacity, and precision machining to improve brake response, reduce fade, and extend pad life under repeated hard stops. Key Features Ultra-light construction: Lowers unsprung and rotational weight for quicker acceleration and crisper braking feel. Premium long-grain carbon iron: Durable casting resists thermal cracking and distortion while providing consistent friction properties. Straight vane cooling: Maximizes airflow and heat transfer for stable temperatures during repeated laps on dirt and pavement. Precision-turned faces: Machined to under 0.001" variation for exceptional flatness and minimal run-out—ensures even pad contact and reduced vibration. 355mm diameter: Optimized for large thermal capacity without excess mass, ideal for oval and dirt-track setups. Benefits Improved lap times through reduced rotational inertia Consistent braking performance under high thermal load Longer rotor and pad life with minimized warping Designed for high-stress rear-axle and competition environments Applications Perfect for dirt track racing, oval competition, and performance rear-axle service on pavement where reliable, repeatable braking and thermal management are critical.
