Its 4-piston hydraulic layout and 12.19-inch rotor diameter need to be checked against the actual hub, upright and wheel arrangement. Bill Wood founded Wilwood Engineering in 1977. Based in Camarillo, California, the company makes disc-brake systems for street-performance, motorsport and specialized applications. Its calipers, brake rotors, master cylinders, valves, fittings and brake lines are selected around the demands of the complete braking installation.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 140-17121-DR; supplied as an axle kit.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing-flange requirement:\u003c\/strong\u003e G-Body flange; 2.62-inch axle offset, measured using the manufacturer worksheet.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor specification:\u003c\/strong\u003e Material: Iron; Type: SRP Drilled Rotor \u0026amp; Hat; Style: SRP Drilled \u0026amp; Slotted; Surface Finish: Black Electro Coat.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor\/hat mounting-hole pattern:\u003c\/strong\u003e 5 x 4.5 in; 5 x 114.3 mm; 5 x 4.75 in; 5 x 120.65 mm; 5 x 5 in; 5 x 127 mm; cataloged hole clearances 0.52 in; 13.21 mm.
