The DBA 4000 Series XS drilled and slotted front rotor for 2001–2007 BMW M3 (E46) with 325mm rotors is a direct replacement rotor that combines high-carbon, heat-treated iron with patented Kangaroo Paw ventilation. The 4000 Series XS Gold variant adds a non-directional cross-drilled and slotted face and a gold-finished rotor hub to aid pad gas and dust escape while providing a distinctive look.
