Product details
This left GT rotor uses the 1.00-inch-wide Spec-37 friction section. The 48 curved vanes determine its side, while the 12.88-inch outside diameter must match both the caliper's radial position and the pad sweep. 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.

Fitment & Compatibility
Use the complete brake kit to establish axle location, caliper spacing and wheel clearance. This 12.88-inch rotor needs a 12 x 8.75-inch mounting interface with 8.25-inch centering. Pad compound and sweep must be suitable for the ring material and 1.00-inch working section. Select pads and operating duty to suit the rotor material and the intended brake system.
