StopTech AeroRotor Replacement Kits (ARK) are designed to replace factory rotors while retaining factory calipers. These kits offer improved cooling, braking, and handling. The directional, floating AeroRotors prevent 'coning' through elongated drive pin holes, allowing independent expansion of the rotor and hat. ARK components include AeroRotor friction rings with patented internal vane design, pre-assembled to billet aluminum AeroHats with directional stand-offs for optimal cooling. The patented AeroRotor vane design increases airflow by up to 80% compared to factory rotors, leading to better cooling and reduced fade. Aircraft-grade aluminum hats and 2-piece AeroRotors are up to 8 pounds lighter than stock, improving acceleration, deceleration, and handling. StopTech AeroRotors are available slotted or cross-drilled to dissipate heat, friction material, and debris, ensuring fresh pad contact. An optional anti-corrosion zinc finish is available for cold climates or for aesthetic preference (no visible surface rust). StopTech AeroRotors are 100% made in the USA.
