GermanAutoParts.com Now Stocking ATE Premium One Rotors Share Comments The ATE Power Disc grooved rotors are back and better than ever. A longtime company favorite, they have been improved and re-named by ATE. Now called ATE Premium One’s, these rotors are still the same high quality upgrade with interlaced elliptical grooves on the braking surface. These grooves both improve stopping power and serve as a visual wear indicator. Additionally, they now feature a MetaCote protective coating, which helps protect unswept areas of rotor against corrosion. Premium One rotors are also now available for both the front and rear axles, so you now have the option to upgrade all four wheels to ATE Premium One performance.
