{"product_id":"wilwood-160-13786-gtb","title":"Wilwood Left 15.00-inch GTB Rotor, Black Slotted Iron with 1.50-inch Width","description":"\u003cp\u003eThis left GTB ring pairs the 15.00-inch diameter with a deep 1.50-inch friction section. Its black finish covers a slotted Spec-37 casting, and both the 9.03-inch register and twelve-on-9.75-inch attachment must match the selected hat. Wilwood Engineering is based in Camarillo, California and was founded by Bill Wood in 1977. It designs and manufactures disc brake systems for motorsport, street-performance and specialized applications. The range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines, all of which require selection around the full brake system rather than an isolated dimension.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 160-13786-GTB\u003c\/li\u003e\n\u003cli\u003eDiameter and thickness: 15.00 inches diameter x 1.50 inches wide\u003c\/li\u003e\n\u003cli\u003eRing material: Spec-37 Iron\u003c\/li\u003e\n\u003cli\u003eFace pattern and coating: GT Slotted; Black electrocoat\u003c\/li\u003e\n\u003cli\u003eInternal layout: 60 CV; curved\u003c\/li\u003e\n\u003cli\u003eMounting direction: Left-hand\u003c\/li\u003e\n\u003cli\u003eBalancing and burnishing: Factory burnished no; balanced yes\u003c\/li\u003e\n\u003cli\u003eOpposite-side component, ordered separately: 160-13785-GTB\u003c\/li\u003e\n\u003cli\u003eRotor-to-hat\/hub attachment circle: 12 x 9.75 inches\u003c\/li\u003e\n\u003cli\u003eAttachment hole size or thread: 0.326 inches\u003c\/li\u003e\n\u003cli\u003eCenter \/ lug registration: 9.03 inches\u003c\/li\u003e\n\u003cli\u003eFar-side inside diameter: 10.55 inches\u003c\/li\u003e\n\u003cli\u003eApproximate component weight: 27.30 lb\u003c\/li\u003e\n\u003cli\u003eQuantity: one rotor ring; hat, hub, mounting hardware, calipers and pads are separate\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eThe 1.50-inch working width must suit the caliper, while the hat centers the ring on its 9.03-inch register.
