The Wilwood GT Series flared-bell rotor hat is precision machined from premium aluminum alloys to combine high strength with low 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 accommodate larger bolt circles and offset ranges typical of big-rotor brake applications when used with matched hardware kits.
