Wilwood Hat-BB Rear .610in Offset 4 x 3.86in - 6 on 6.25in

This is the Wilwood GT Series rear brake rotor hat, designed for big brake applications where space is tight. It features a short offset, measuring less than 1.00 inch, making it ideal for narrow applications. The hat is precision machined from aluminum alloys, which keeps the weight down while maintaining strength. It has threaded holes for mounting standard through-hole rotors, and can also be used with T-Nuts or bobbins for specially machined slotted hole rotors. When paired with the correct Wilwood rotor hardware kits, these hats offer solid, dependable performance.

This hat is available for a variety of rotor bolt patterns and wheel patterns, including four and six lug configurations. The 4 x 3.86 inch bolt pattern for the wheel and the 6.25 inch bolt circle for the rotor are specific to certain applications, so it's important to verify fitment for your setup. These hats are a well-built component for anyone looking to upgrade their braking system with a big brake kit.
