The DBA 5000 Series T-Slot replacement rotor ring fits 1997–2012 Chevrolet Corvette applications and is intended as the ring component for two-piece rotor setups. 5000 Series flat discs let you replace just the rotor ring without swapping the hat, and the T3 bi-directional slot option provides a directional slot pattern developed to improve pad bite and evacuation compared with plain discs.
