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

Wilwood UL-32 Ultra-Light Directional Vane Rotors for Sportsman Racing Purpose-built for competitive sportsman racing , the Wilwood UL-32 Ultra-Light rotors combine directional vane cooling, race-grade materials, and minimal rotating mass to deliver consistent stopping power lap after lap. Directional vane airflow — Engineered vane geometry accelerates air movement through the disc for rapid heat rejection on stop-and-go dirt tracks and high-speed pavement braking. Long-grain carbon iron construction — High-strength casting provides extended pad life, superior thermal stability, and reduced risk of warping under extreme temperature cycles. Ultra-light design — Significantly lower rotating and unsprung mass improves acceleration, transient response, and rotational inertia — ideal for rear-axle applications and tight-setup chassis. Production-machined accuracy — CNC-like finish and balanced assembly ensure true running, predictable pedal feel, and quick installation across many sportsman classes. Race-proven reliability — Designed to withstand repeated heavy use while maintaining consistent pad contact and fade resistance during extended events. Choose Wilwood UL-32 rotors when you need a lightweight, durable braking solution that prioritizes cooling efficiency and repeatable performance under the rigors of dirt or pavement competition.
