{"product_id":"wilwood-160-16511-gtb","title":"Wilwood Front GM 1500 GT Rotor and Hat, 13.38 x 1.25 Inches","description":"\u003cp\u003eThe 13.38-inch AERO6-DM front brake package uses this GT rotor and integral hat to retain the intended caliper-to-rotor relationship. Its 48-vane iron casting combines a 1.25-inch friction section with a 0.680-inch offset and black electro-coat finish. 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 160-16511-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 13.38 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 Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 48 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 26.14 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 Non-directional\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegistration \/ lug inside diameter:\u003c\/strong\u003e 3.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFar-side inside diameter:\u003c\/strong\u003e 9.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor offset:\u003c\/strong\u003e 0.680 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternal clearance diameter:\u003c\/strong\u003e 7.30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting-face thickness:\u003c\/strong\u003e 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHat wheel-stud clearance pattern:\u003c\/strong\u003e 6 x 5.50 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel-stud clearance hole diameter:\u003c\/strong\u003e 0.63 inches\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\u003eFor compatible GM 1500 Wilwood AERO6-DM installations, including the packages identified in DS1522 and DS1590.
