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

Wilwood ULHP-32 Ultra-Light 355mm Straight Vane Rotors — Dirt Track Performance Brand: Wilwood The ULHP-32 Ultra-Light 355mm straight vane rotors are engineered for dirt track competition and pavement rear-axle upgrades, delivering race-proven stopping power while reducing rotating mass for quicker deceleration and sharper handling under heavy braking. Optimized cooling: Straight vane architecture promotes consistent airflow to dissipate heat during repeated hard stops and reduce fade. Ultra-light construction: Reduced unsprung and rotational mass improves throttle response, suspension control, and lap-to-lap consistency. Premium iron alloy: Cast from long-grain, high-grade carbon iron for superior wear life, thermal stability, and resistance to warping. Precision machined faces: Turned to tight tolerances with under .001" variation in flatness, parallelism, and run-out for smooth operation and consistent pad engagement. 355mm diameter: Balanced size offering the torque and modulation needed for dirt track dynamics and rear-axle pavement applications. Designed for durability, thermal control, and exacting fitment, the Wilwood ULHP-32 rotors help maintain predictable braking performance lap after lap — ideal for drivers demanding competitive advantage and reliability.
