StopTech AeroRotor Replacement Kits (sold in pairs) have been designed to replace your vehicle's original factory rotors, while retaining the factory brake calipers. Although the ARK is the same diameter and thickness as the factory rotors to the fit is perfect, it offers improved cooling, braking, and handling. The patented AeroRotor vane design pushes up to 80% more air than factory rotors for better cooling and reduced fade on the track. 

Cross-drilled rotors allow better dissipation of heat, friction material and debris, assuring that fresh pad material is in contact with the rotor every time the brakes are applied. The aluminum hats and 2-piece AeroRotors are up to 8 pounds lighter than stock rotors, allowing faster acceleration and deceleration, and improved handling.

StopTech Aerovanes 
The patented 2-piece AeroRotor assembly uses uniquely designed and patented AeroVanes inside the disc to optimize airflow through the rotor. This improved directional design minimizes turbulence and flows up to 61 percent more air than any other rotor tested. 

The result is up to 80 percent better airflow over original equipment rotors and 10-30 percent better airflow than other directional vane racing rotors currently available. Better airflow equals better cooling, and better cooling means less fade and better overall brake system performance.

StopTech Zinc Plating 
Zinc Plating, available on StopTech AeroRotors, prevents corrosion. This is particularly useful in winter climates where road salt and other environmental factors may increase the likelihood of oxidation.
