STR40/34-38/32

StopTech AeroRotor Replacement Kits (ARK) provide improved cooling, braking, and handling compared to factory rotors, while retaining the factory calipers. Featuring directional, floating AeroRotors with elongated drive pin holes, they allow independent expansion of the rotor and hat. ARK includes AeroRotor friction rings with a patented internal vane design, pre-assembled to billet aluminum AeroHats with directional stand-offs for optimized cooling. The patented AeroRotor vane design increases airflow by up to 80% for better cooling and reduced fade. Made from aircraft-grade aluminum, the hats and 2-piece AeroRotors are up to 8 pounds lighter than stock, enhancing acceleration, deceleration, and handling. Available slotted or cross-drilled for improved heat, friction material, and debris dissipation. An optional anti-corrosion, zinc finish is offered for cold climates or aesthetic preference, preventing visible surface rust. 100% made in the USA.
