Wilwood Right GT Dynamic Rotor, 13.06 x 1.25-inch, 8.80-inch Lug Interface

This right-hand GT rotor uses the larger dynamic interface with a 13.06-inch friction diameter. Its unburnished 1.25-inch ring has 48 curved vanes and twelve mounting lugs for the corresponding carrier and retention arrangement. Disc brake systems and components are the work of Wilwood Engineering, founded by Bill Wood in 1977 and based in Camarillo, California. The company designs and manufactures calipers, brake rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications, with each component selected to match the complete system.

Fitment & Compatibility

The 8.80-inch dynamic carrier must engage all twelve lugs and use its specified retainer. Verify caliper placement for the 13.06-inch outside diameter and 1.25-inch friction section, then check right-hand vane orientation. The mounting interface does not use conventional rotor bolts.
