The DBA 5000 Series two-piece drilled-and-slotted front rotor for 2005–2006 Pontiac GTO (black hat) is a sport-oriented replacement ring and hat combination that reduces rotating mass and improves heat dissipation. The two-piece design pairs a steel ring with an aluminum hat for lighter weight and lower maintenance, while the XS cross-drilled and slotted face offers improved pad clearing and braking response.
