The Wilwood GT Series flared-bell rotor hat is precision machined from premium aluminum alloys for high strength with attention to reduced weight. Threaded rotor mount holes accept standard through-hole rotors and may be used with T-nuts or bobbins for dynamic mounting. Flared-bell hats are typically specified for larger bolt circles and offset ranges required by big-rotor brake applications.
