The DBA 4000 Series drilled and slotted rotor for 2000-2002 Audi S4 rear brakes is a direct-replacement single-piece rotor built from high-carbon, heat-treated iron with DBA's Kangaroo Paw ventilation. The XS-style drilled and slotted pattern evacuates pad dust and gases while improving bite; the Gold hub finish on XS variants adds corrosion resistance and visual appeal.
