The DBA 5000 Series drilled-and-slotted front rotor (black hat) for the 2009 Chevrolet Corvette ZR1 is a two-piece XS rotor combining a steel ring with an aluminum hat for lighter weight and improved heat dissipation. The XS non-directional cross-drilled and slotted face enhances pad clearing and braking performance, while the two-piece design reduces rotational mass and simplifies maintenance or upgrades.
