{"product_id":"wilwood-160-3747","title":"Wilwood Ultralite 30-Vane Rotor, 10.25 x 0.75 Inches, Plain Face","description":"\u003cp\u003eAt 10.25 inches, this Ultralite rotor has a smaller working diameter than the otherwise similar 10.50-inch ring. It retains a 0.75-inch vented section and 30 straight vanes, with plain faces and a six-hole attachment flange. Wilwood began in 1977 with founder Bill Wood and is based in Camarillo, California, where it designs and manufactures disc brake systems. Calipers and rotors sit alongside master cylinders, valves, fittings and lines in a range serving motorsport, street performance and specialized applications. Selecting these parts together is essential to a correctly matched brake installation.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-3747\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 10.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 0.75 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 30 vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e Plain Face\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 6.10 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 6 x 5.50 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 4.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 6.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e Suitable for moderate-temperature racing and street use.
