{"product_id":"wilwood-160-12290","title":"Wilwood Left Plain-Face HD Rotor in Spec-37 Iron, 12.19-inch by 0.81-inch","description":"\u003cp\u003eThe left HD ring combines smooth contact faces with a narrow 0.81-inch friction section. At 12.19 inches in diameter, it must sit at the correct radial and axial position inside the intended caliper rather than simply share the hat's bolt pattern. The manufacturer is Wilwood Engineering of Camarillo, California, founded by Bill Wood in 1977. It designs and manufactures disc brake systems, supplying calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications. Matching this component requires consideration of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 160-12290\u003c\/li\u003e\n\u003cli\u003eOutside diameter \/ width: 12.19 inches diameter x 0.81 inches wide\u003c\/li\u003e\n\u003cli\u003eMaterial specification: Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFriction surface \/ finish: Plain Face; Plain\u003c\/li\u003e\n\u003cli\u003eVentilation: 36 CV; curved\u003c\/li\u003e\n\u003cli\u003eMounting direction: Left-hand\u003c\/li\u003e\n\u003cli\u003ePreparation: Balanced: no; factory burnished: no\u003c\/li\u003e\n\u003cli\u003eOpposite-side component, ordered separately: 160-12289\u003c\/li\u003e\n\u003cli\u003eRotor-to-hat\/hub attachment circle: 8 x 7.00 inches\u003c\/li\u003e\n\u003cli\u003eAttachment hole size or thread: 0.326 inches\u003c\/li\u003e\n\u003cli\u003eCenter registration: 6.38 inches\u003c\/li\u003e\n\u003cli\u003eFar-side inside diameter: 8.56 inches\u003c\/li\u003e\n\u003cli\u003eApproximate weight: 9.50 lb\u003c\/li\u003e\n\u003cli\u003eQuantity: one rotor ring; hat, hub, mounting hardware, calipers and pads are separate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eSelect the separate hat for the 8 x 7.00-inch rotor-attachment pattern and 6.38-inch register.
