{"product_id":"wilwood-270-12788","title":"Wilwood Front Cadillac Vented-Rotor Hub (1941–1955), 5 x 5.00-Inch Wheel Flange","description":"\u003cp\u003eThis Cadillac front hub is single drilled on a five-on-five wheel circle. It supports a separate rotor plate and requires the specified press-on bearing cap in addition to the correct spindle bearings. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-12788\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Bare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel mounting pattern(s):\u003c\/strong\u003e 5 x 5.00 inches; separate from rotor or drive-flange attachment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel-stud thread:\u003c\/strong\u003e 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting arrangement:\u003c\/strong\u003e Adapter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor interface:\u003c\/strong\u003e 5 x 3.88; this is not the wheel bolt circle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible rotor-adapter output interface(s):\u003c\/strong\u003e 6 x 6.25, 8 x 7.00; match the actual adapter and rotor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct-page drawing references (inches):\u003c\/strong\u003e A = 1.820; D = 2.624; H = 1.394; M = 3.700; N = 2.320; P = 3.040; Q = 0.250.
