{"product_id":"wilwood-160-5865","title":"Wilwood Ultralite Drilled Dirt-Racing Rotor, 12.19 x 0.81 Inches","description":"\u003cp\u003eThe larger 12.19-inch race-drilled ring maintains a 0.81-inch vented section for the corresponding dirt-racing assembly. Its iron casting is extensively drilled and should be chosen for the approved racing duty, not simply for its lower mass. Camarillo, California is home to Wilwood, founded by Bill Wood in 1977. The company designs and manufactures disc brake systems for motorsport, street performance and specialized applications, supplying rotors, calipers, master cylinders, valves, fittings and lines. Matching the rotor to the complete assembly matters as much as selecting its diameter or surface treatment.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-5865\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e One rotor; not an axle pair\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside diameter:\u003c\/strong\u003e 12.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor material:\u003c\/strong\u003e Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 32 vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e Race Drilled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Plain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate weight:\u003c\/strong\u003e 8.00 lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory burnished:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamically balanced:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation orientation:\u003c\/strong\u003e Non-directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor attachment pattern:\u003c\/strong\u003e 8 x 7.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hole \/ thread:\u003c\/strong\u003e 0.326 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 6.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 8.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e For light to moderate dirt racing.
