The DBA 4000 Series cross‑drilled rotor for 2011–2018 Porsche Cayenne (360mm front iron rotor) uses a non‑directional cross drilled and dimpled XD design to improve cooling over standard HD finishes. Cast from high carbon alloyed iron and heat treated, the XD finish adds extra cooling benefits and a sportier aesthetic while remaining a direct replacement rotor suited to heavier braking loads.
