{"product_id":"wilwood-160-8747","title":"Wilwood Left-Hand GT Ring with Twelve-on-7-Inch Mount, 12.60-Inch Spec-37 Rotor","description":"\u003cp\u003eThis left-hand GT ring places a 12.60-inch slotted friction surface around a compact twelve-bolt mounting center. The 1.25-inch Spec-37 section and 48 curved vanes suit the corresponding complete brake assembly, with a listed 15.60-lb weight. Founded by Bill Wood in 1977, Wilwood designs and manufactures disc brake systems in Camarillo, California. Its range includes calipers, rotors, master cylinders, valves, fittings and lines for motorsport, street performance and specialized applications.
