Wilwood HD Fixed Mount Brake Rotor Hats

These Wilwood HD fixed mount brake rotor hats are manufactured from a premium-grade aluminum alloy offering high strength, low weight, and show-quality appeal. They feature straight bell construction with a flanged rotor mount ring. These rotor hats provide maximum radial clearance between the caliper body and the hats. They require the use of the correct Wilwood rotor bolt pattern for installation.
