The DBA 5000 Series XS two-piece drilled-and-slotted rotor for 2005-2009 Audi A4 Quattro front pairs high-carbon cast-iron rings with a lighter aerospace-grade aluminum hat to reduce unsprung weight and improve heat dissipation. The XS non-directional cross-drilled and slotted pattern enhances pad dust evacuation and cooling; a gold hat finish is available for a sportier appearance and reduced maintenance costs.
