Wilwood Hat-BB Front .1.20in Offset 5 x 4.75 - 12 on 8.75in

This is the Wilwood GT Series Big Brake flared bell hat, designed for custom brake builds. It's precision machined from premium aluminum alloys, which means it's strong but also keeps weight down. This hat features threaded rotor mount holes, so you can use it with standard through-hole mount rotors, or with T-Nuts or bobbins if you're using specially machined slotted hole dynamic mount rotors.

The flared bell design is generally used with rotor mount bolt circles of 8.38 inches and larger. This specific hat has a 1.20-inch offset and accommodates a 5 x 4.75 bolt circle, with a 12-inch diameter rotor mounting area and an 8.75-inch brake hat diameter. When paired with the correct Wilwood rotor hardware kits, these hats offer solid, reliable performance for your custom brake setup.
