Wilwood Ultra-Light ULHP-32 straight vane rotors provide an excellent balance of efficient cooling and lower rotating mass on hard braking dirt tracks or rear axle service on pavement cars. UL rotors are cast from premium grade, long grain carbon iron for long wear, high thermal stability, and resistance to distortion. ULHP-32 rotors offered the added performance and smoother operation of precision turned faces with less than .001″ variation in flatness, parallelism, or run-out.
Wilwood SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight.
Wilwood ULS-32 scalloped iron rotors provides effective lightweight options for sprints late models modifieds and other competition applications that race in low to medium temperature ranges.
