Wilwood's New Type III hard-anodized aluminium 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 10.20" rotor mounts directly outboard on 42 spline 2.75" Sprint Car axles.

Wilwood's specifically engineered drilled pattern for each rotor, along with Type III hard-anodized aluminium, 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 PolyMatrix Q compound brake pads with these rotors.

• Hard-anodized for greater friction and longer life than other aluminium rotors
• Lowest thermal distortion and run-out of any aluminium rotors
• Withstands higher heat than competitor's aluminium rotors
