The Wilwood GT Series flared-bell rotor hat combines precision machining and premium aluminum alloys for high strength with minimal weight. Threaded rotor mount holes accept standard through-hole rotors and may be used with T-nuts or bobbins for dynamic mounting. These hats are intended for larger rotor bolt circles and offset ranges typically required by big-rotor brake applications.
