The DBA 4000 Series drilled rear rotor for 2007–2015 Audi Q7 uses DBA's XD non-directional cross-drilled and dimpled design to add cooling benefits and visual appeal. As a direct-replacement disc, it pairs the drilled XD finish with the 4000 Series' materials and manufacturing approach to improve heat dissipation and maintain consistent braking behavior under repeated heavy use.
