The Wilwood GT Series flared-bell rotor hat is precision machined from premium aluminum alloys to deliver a high-strength, lightweight mounting solution. Threaded rotor mount holes work with standard through-hole rotors and can accept T-nuts or bobbins for dynamic mounting. These hats are intended for larger rotor bolt circles and the offset ranges associated with big-rotor brake installations.
