{"product_id":"wilwood-160-8745-bk","title":"Wilwood Rear Left-Hand 12.19-Inch SRP Rotor and Hat for Pontiac GTO","description":"\u003cp\u003eA left-hand SRP surface orientation identifies this rear rotor for the corresponding side of the Pontiac GTO package. The black-finished iron casting carries the 12.19-inch friction face and parking drum in one piece, with a 2.310-inch offset. 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 160-8745-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 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 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 15.80 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 Left-hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 2.76 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 6.70 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor offset:\u003c\/strong\u003e 2.310 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal parking-brake drum diameter:\u003c\/strong\u003e 7.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal clearance diameter:\u003c\/strong\u003e 6.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting-face thickness:\u003c\/strong\u003e 0.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHat wheel-stud clearance pattern:\u003c\/strong\u003e 5 x 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel-stud clearance hole diameter:\u003c\/strong\u003e 0.52 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpposite-hand companion rotor:\u003c\/strong\u003e 160-8744-BK (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntended use and restrictions:\u003c\/strong\u003e Rear rotor for compatible Pontiac GTO kits with an internal parking drum.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe integral hat is part of the rotor; caliper, pads, parking-brake mechanism and installation hardware are separate.\u003c\/p\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eVerify the full GTO rear brake setup before ordering.
