Wilwood Front Red Superlite GTO Conversion (2004–2006), Drilled/Slotted 13.06-Inch Rotors & Flexlines

This GTO front conversion brings together red Superlite 6R calipers, 13.06-inch SRP rotors and the matching hydraulic hose package. The rotor hats retain the original hub interface; the installation instructions distinguish the 2004 mounting details from later cars. From its base in Camarillo, California, Wilwood Engineering designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. Founded by Bill Wood in 1977, the company also produces the individual calipers, brake rotors, master cylinders, valves, fittings and brake lines used in these installations. Selection should account for how each component works within the complete brake system.
