The Centric Parts StopTech AeroRotor Replacement Kits (ARK) offer a range of OE-sized, two-piece replacement rotors designed to improve brake system performance by utilizing factory brake calipers. Available in drilled or slotted form, these U.S.A.-made rotors are available for dozens of high-performance vehicle applications. According to the company, StopTech ARKs provide shorter stopping distances, better brake modulation, firmer pedal feel and less brake fade. StopTech ARK components include billet aluminum StopTech AeroHats with directional stand-offs that optimize cooling airflow; StopTech AeroRotor friction rings with AeroVanes that push up to 80 percent more air than factory rotors; and Inconel drive pin washers that are practically impervious to oxidation or corrosion.
