Wilwood 160-7102-BK SRP Drilled & Slotted Performance 11.75 Left Black - USA-WIL-160-7102-BK - SRP Drilled Performance Rotor 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. Performance Characteristics Premium grade, medium weight castings. Suitable for moderate temperature racing to street use. For ultimate durability in racing use comparable ULHP or GT rotors.
