{"product_id":"wilwood-160-8397-bk","title":"Wilwood Left-Hand 14-Inch SRP Spec-37 Rotor, 1.25-Inch Friction Section","description":"\u003cp\u003eThe left-hand surface and vane orientation define this SRP ring for the corresponding side of a 14-inch assembly. Its 1.25-inch Spec-37 section is paired with a 72-vane core and black-finished casting. 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 160-8397-BK\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 14.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal thickness:\u003c\/strong\u003e 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor material:\u003c\/strong\u003e Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 72 curved vanes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriction surface:\u003c\/strong\u003e SRP Drilled \u0026amp; Slotted\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black Electro Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproximate weight:\u003c\/strong\u003e 17.40 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 Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation orientation:\u003c\/strong\u003e Left-hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor attachment pattern:\u003c\/strong\u003e 12 x 8.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor mounting hole \/ thread:\u003c\/strong\u003e 0.251 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 8.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 10.00 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpposite-hand companion rotor:\u003c\/strong\u003e 160-8396-BK (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e For racing durability, Wilwood recommends comparable GT rotors.
