The selected six-piston package uses BP-20 pads, separate aluminum rotor hats and application-specific front hoses. It must correspond to the vehicle's compatible original hub and upright configuration, with wheel clearance established before ordering this larger-diameter conversion. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company designs and manufactures disc brake systems and components, including calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications.\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-12929-R\u003c\/li\u003e\n\u003cli\u003eType: AERO6 Big Brake Front Brake Kit.\u003c\/li\u003e\n\u003cli\u003eCalipers: AERO6; 6-piston; Red Powder Coat.\u003c\/li\u003e\n\u003cli\u003ePiston bore dimensions: 1.62, 1.12, 1.12 inches; stainless pistons.
