It is the vented-offset option for the conversion and should be selected with the intended rotor and caliper bracket geometry. Wilwood Engineering designs and manufactures complete disc brake systems as well as calipers, brake rotors, master cylinders, valves, fittings, and brake lines. Based in Camarillo, California, it was founded by Bill Wood in 1977. The range serves motorsport, street-performance, and specialized applications, requiring each part to be matched to the system in which it operates.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 270-8775\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\u003ePosition:\u003c\/strong\u003e Front\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel bolt pattern:\u003c\/strong\u003e 5 x 4.75 in; 5 x 4.50 in\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 adapter patterns:\u003c\/strong\u003e 6 x 6.25 in; 8 x 7.00 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor adapter options:\u003c\/strong\u003e 300-3307 six-bolt \/ 300-3099 eight-bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.5 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner bearing specification:\u003c\/strong\u003e 370-0884 \/ A13 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter bearing specification:\u003c\/strong\u003e 370-0877 \/ A2 set (fitment reference)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrawing dimension N:\u003c\/strong\u003e 2.310 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eConfirm that the vehicle retains the specified disc-brake spindle.
