Wilwood's 3 hole mount rotors are precision CNC machined from high strength billet plate. These rotors fit the popular 3 x 5.00 in mount bolt circle found on most sprint and midget front hubs. Wilwoods engineered drill slot pattern combines the highest degree of weight reduction with the highest resistance to thermal distortion in the contact faces. Wilwood's New Type III hard-anodized aluminum rotor finish improves performance and increases life over all other aluminum rotors. Precision CNC machined from high strength billet, full symmetrical machining provides perfect balance, flatness, and the truest rotation of any rotor made. This 10.95 rotor fits the 3 x 5.00 in mount bolt circle for Sprint Car and Midget front hubs. Wilwood's specifically engineered drilled pattern for each rotor, along with Type III hard-anodized aluminum, combines the greatest weight reduction with the highest resistance to thermal distortion. This design's low knock-back characteristics give lap after lap of smooth engagement and a consistent full pedal. For best results, use Purple compound brake pads with these rotors. Hard-anodized for greater friction and longer life than other aluminum rotors Lowest thermal distortion and run-out of any aluminum rotors Withstands higher heat than competitor's aluminum rotors
