Wilwood Hat-BB Front 1.62in Offset 5 x 4.75 - 12 on 8.75in

If you're building a custom big brake setup for your vehicle, the Wilwood GT Series Big Brake Flared Bell Hat is a key component. This hat is precision machined from premium aluminum alloys, which means it's strong enough for demanding conditions while also being lightweight. It's designed to work with standard through-hole mount rotors, featuring threaded mounting holes for a secure connection. You can also use it with T-Nuts or bobbins if you're using specially machined slotted hole dynamic mount rotors.

This particular hat has a 1.62-inch offset and a 5 x 4.75-inch bolt circle, with a 12-inch rotor diameter and an 8.75-inch hat diameter. When paired with the correct Wilwood rotor hardware kits, these hats offer solid and reliable performance. They are generally used with rotor mount bolt circles of 8.38 inches and larger, and offsets range from 1.88 to 3.00 inches for rotor diameters 12.19 inches and up.
