DBA 5000 Series cross-drilled and slotted rotor rings for the 2004 WRX STi (5x100) are replacement rings for two-piece rotor configurations. The 5000 Series flat discs are designed to replace just the ring and are available in multiple slot, drill and vent designs. They provide stamped design options and finishes intended to refresh braking surfaces without replacing the entire two-piece rotor.
