StopTech 07-09 Audi RS4 Front Slotted Bare Iron 365x34mm AeroRotor Kit (Pair)

The StopTech AeroRotor Replacement Kit (ARK) upgrades vehicle braking by replacing factory rotors while retaining existing calipers. It enhances cooling, braking performance, and handling. AeroRotors feature a directional, floating design that allows independent expansion of the rotor and hat, preventing "coning." Patented internal vane design and directional stand-offs on billet aluminum AeroHats optimize cooling airflow, pushing up to 80% more air than factory rotors, reducing fade. Aircraft-grade aluminum hats contribute to an up to 8-pound weight reduction compared to stock rotors, improving acceleration, deceleration, and handling. Available in slotted or cross-drilled options, which dissipate heat, friction material, and debris for consistent pad contact. An optional anti-corrosion zinc finish is available for harsh climates. All StopTech AeroRotors are 100% made in the USA.
