Complete source-backed product details
AeroRotors and AeroHats offer up to 61% greater airflow. StopTech has developed several design innovations to improve rotor airflow. The patented 2-piece AeroRotors push more air thanks to curved, airfoil-shaped vanes and an air channel that widens at the trailing edge of the vanes. StopTech aluminum AeroHats are lighter, and feature directional stand-offs between the rotor and mounting hat that increase airflow to the (hotter) outside face of the rotor by over 15%.
