Wilwood Hat-Dynamic BB Front 1.38in Offset 5 x 4.50 - 12 on 8.75in

Precision machined from aluminum, these GT Series Dynamic Mount Rotor Hats are built to handle the demands of motorsports competition. They offer a great combination of high strength and low unsprung and rotating weight, which is crucial for performance driving. The unique T-nut design floats within the hat, allowing for true dynamic mounting of standard through-hole rotors. This setup, along with the wide load-bearing surface of the T-nut and straight through-hole mount rotors, offers a durable and accurate way to isolate pad engagement harmonics and thermal variations between the hat and the rotor.

This hat features a 1.38-inch offset and a 5 x 4.50 bolt circle pattern, with a 2.800-inch register diameter. It's designed for a 12-inch rotor with an 8.75-inch bolt circle, making it a solid option for performance brake builds where precise component isolation and weight savings are key.
