Its clamp arrangement is intended for a 3.00-inch, 46-spline sprint axle and a sidebell with 3.50-inch mounting centers. BP-40 pads and Thermlock pistons belong to this racing configuration; road-car model or axle-family names do not establish compatibility. Wilwood Engineering was established in 1977 by Bill Wood in Camarillo, California. The company designs and manufactures disc-brake systems and components, from calipers and rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized installations. Each component must match the rest of the brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 140-15815.
