Wilwood Hat-BB Front .1.50in Offset 5 x 4.75 - 12 on 8.75in

When you're building out a custom brake setup, especially for a performance application, the rotor hat is a critical component. This Wilwood GT Series flared bell hat is precision machined from aluminum alloys, which means it's strong but also keeps weight down. This specific hat has a 1.50-inch offset and a 5 on 4.75-inch bolt circle pattern, designed to work with rotors that measure 12 inches in diameter and have an 8.75-inch mount pattern.

These hats feature threaded rotor mount holes, so you can use standard through-hole rotors. They're also set up to work with T-Nuts or bobbins if you're using specially machined slotted hole rotors. When paired with the right Wilwood rotor hardware kits, these hats offer a solid foundation for reliable brake performance.
