USR automotive brake discs are a new series available for selected car models, offering much quieter braking than Turbo Groove discs. USR discs are covered with the latest technology of a coating that protects against the occurrence of too early corrosion centers. These are standard-size replacements of original spare parts in black, subjected to cosmetic surface incisions, which give a lot of benefits, significantly accelerating cleaning and drying of the discs, and reduction of gas pressure under the pads.
