Product details
The black HPS rotor combines a slotted 12.88-inch friction ring with a cast-in hat. Its 1.10-inch width, 1.75-inch offset and dual five-lug clearance patterns must match the existing hub and caliper assembly. Wilwood Engineering's disc brake systems are designed and manufactured for motorsport, street-performance and specialized applications. Founded in 1977 by Bill Wood and based in Camarillo, California, the company makes calipers, brake rotors, master cylinders, valves, fittings and brake lines. These individual parts must be chosen to work within the complete braking system.

Fitment & Compatibility
Front rotor for the matching 12.88-inch conversion, including kit 140-13654. Its 1.75-inch hat offset, 3.06-inch register and dual stud-clearance circles require the corresponding hub and caliper bracket. Confirm the supplied vane count because the manufacturer's table and family description differ.
