Wilwood GT Series Big Brake Flared Bell hats are engineered for high-performance braking systems where high strength and minimal unsprung weight are critical. Precision machined from premium aluminum alloys, these hats provide a stable and reliable mounting platform for rotors under demanding racing or high-performance street conditions.

This specific flared bell design (MPN 170-8883) features threaded rotor mount holes, making it compatible with standard through-hole mount rotors. The threaded hole configuration also allows for versatile setups using T-Nuts or bobbins when paired with specially machined slotted-hole dynamic mount rotors. For the most secure installation, use these hats in conjunction with matched Wilwood rotor hardware kits.
