2PC AeroRotor Hat Pair

StopTech AeroRotor Replacement Kits (ARK) replace factory rotors while retaining factory calipers. They offer improved cooling, braking, and handling with the same diameter and thickness as OEM. Directional, floating AeroRotors allow independent expansion to prevent 'coning.' ARK includes AeroRotor friction rings with patented internal vane design and billet aluminum AeroHats with directional stand-offs for optimized cooling. The patented AeroRotor vane design pushes up to 80% more air than factory rotors, reducing fade. Aircraft-grade aluminum hats and 2-piece AeroRotors are up to 8 pounds lighter than stock, enhancing acceleration, deceleration, and handling. Available slotted or cross-drilled for better heat, friction material, and debris dissipation. An optional anti-corrosion zinc finish is available for cold climates and to prevent visible surface rust. 100% made in the USA.
