{"product_id":"wilwood-160-8399-gtb","title":"Wilwood Left-Hand GT Rotor, 14 x 1.25 Inches, Black-Coated 72-Vane","description":"\u003cp\u003eThe black electro-coated left-hand GT rotor adds a protective finish to the 14-inch Spec-37 casting. Its 72-vane core, slotted friction faces and thick 1.25-inch section remain matched to the specified twelve-bolt brake assembly. Wilwood’s calipers, rotors, master cylinders, valves, fittings and lines support complete disc brake systems rather than an isolated component choice. Founded in 1977 by Bill Wood and based in Camarillo, California, the company designs and manufactures these systems for motorsport, street performance and specialized applications. Correct pairing of the rotor with its surrounding hardware is essential.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 160-8399-GTB\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 GT 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 17.50 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 160-8398-GTB (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e Suitable for high-temperature racing and street use.
