Wilwood Hat-BB Front .715in Offset 5 x 4.50 - 12 on 8.75in

Precision machined from aluminum alloys, these Wilwood GT Series Big Brake hats are built for strength while keeping weight down. They feature threaded rotor mount holes, meaning you can use them with standard through-hole mount rotors, or with T-Nuts or bobbins if you're using specially machined slotted hole dynamic mount rotors. These short offset hats are designed for applications where space is tight, typically with offsets less than 1.00 inch. They are available for a variety of wheel bolt patterns, including the 5 x 4.50 inch pattern this one is made for.

When paired with the correct Wilwood rotor hardware kits, these hats offer solid, reliable performance. The specific dimensions here are a 12-inch bolt circle, 5 x 4.50 and 4.75 inch mount patterns, a .635 inch offset, and a 3.064 inch register diameter. This makes them a well-built option for custom brake setups where precise fitment in narrow spaces is key.
