Wilwood Hat-BB Front .850in Offset 5 x 5.00 - 12 on 8.25in

Precision machined from aluminum alloys, these Wilwood GT Series Big Brake flared bell hats are built for strength while keeping weight to a minimum. They feature threaded rotor mount holes, designed to work with standard through-hole mount rotors. You can also use them with T-Nuts or bobbins if you're running specially machined slotted hole dynamic mount rotors.

When paired with the correct Wilwood rotor hardware kits, these hats offer solid, dependable performance. The flared bell design is typically used with rotor mount bolt circles of 8.38 inches and larger, and this specific hat has a 0.850-inch offset, a 5 x 5.00 inch bolt circle, and fits 12-inch rotors on an 8.25-inch diameter mounting surface.
