Wilwood Left 15.00-inch GT Slotted Rotor, Plain-Finish Spec-37 Iron, 1.25-inch Wide

The left GT rotor supplies a fifteen-inch slotted friction ring in the 1.25-inch width. Its 72 curved cooling vanes and 8.25-inch register establish orientation and centering within the separate-hat brake assembly. The broader Wilwood range covers calipers, brake rotors, master cylinders, valves, fittings and brake lines. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California, designing and manufacturing disc brake systems for motorsport, street-performance and specialized applications. Individual components must be coordinated with the complete braking system.

Fitment & Compatibility

For an assembly designed around a 15.00 x 1.25-inch friction ring. Use the correct rotor fasteners and hat, checking both the 12 x 8.75-inch attachment circle and the 8.25-inch registration. Determine axle suitability from the complete brake kit, not from the rotor's diameter. Select pads and operating duty to suit the rotor material and the intended brake system.
