The Wilwood GT Series flared-bell rotor hat is machined from premium aluminum alloys to balance high strength and low weight. Threaded rotor mount holes accept standard through-hole rotors and can work with T-nuts or bobbins for dynamic mount configurations. Flared-bell hats suit larger rotor mount bolt circles and the offsets typically required by big-rotor brake kits, offering reliable performance with matched hardware.
