TWO PIECE AEROROTOR AND HAT PAIR

StopTech AeroRotor Replacement Kits (ARK) are 2-piece rotors designed to replace factory rotors while retaining factory brake calipers. They feature directional, floating AeroRotors with elongated drive pin holes, allowing independent expansion of the rotor and hat without "coning." ARK components include AeroRotor friction rings with a patented internal vane design, pre-assembled to billet aluminum AeroHats with directional stand-offs for optimized cooling airflow. The patented AeroRotor vane design pushes up to 80% more air than factory rotors, leading to better cooling and reduced fade on the track. The aircraft-grade aluminum hats and 2-piece AeroRotors are up to 8 pounds lighter than stock rotors, contributing to faster acceleration, deceleration, and improved handling. Available in slotted or cross-drilled configurations for heat dissipation and fresh pad material contact. An optional anti-corrosion zinc finish is available. 100% made in the USA.
