HAT

StopTech AeroHats are made with a special type of billet aluminum, designed for the Aerospace industry. They feature directional stand offs between the rotor and mounting bell (hat) that increase airflow to the outside faces of the rotor by 50-100%. This increased airflow reduces the temperature difference between the inside and outside faces of the rotor, resulting in less distortion and better performance compared to other fully floating designs. Outer pad wear is also reduced. AeroHat improves entire brake system airflow by up to 4%. These hats are machined to ISO standards at StopTech’s manufacturing facility in Torrance, California, using the latest CNC machines that feature active tooling.
