Wilwood Hat-BB Front .814in Offset 5 x 4.50 - 12 on 8.75in

This Wilwood brake rotor hat is precision machined with threaded holes, specifically designed to work with Wilwood's internal shoe parking brake kits and through-hole mount rotors. The hat itself is made from well-built cast iron and measures 12 inches in diameter with an 8.75-inch bolt circle pattern, accommodating a 5 x 4.50 bolt circle. It features a .814-inch offset, which is a critical measurement for ensuring proper clearance and alignment with your brake system components.

After machining, these hats receive an electro-coating to help protect them from corrosion, keeping them looking good and functioning properly over time. This component is a key part of a two-piece rotor assembly, allowing for easier replacement of wear items like the rotor ring while keeping the hat intact. It's a solid option if you're building or upgrading a braking system that requires an integrated parking brake function.
