What to Expect
The DBA 4000 Series T3 is a factory-size, one-piece rotor upgrade rather than a big-brake conversion. It retains the original C8 Corvette Stingray Z51 rear calipers and mounting points while adding DBA’s T3 slot pattern, high-carbon iron construction, and performance-focused ventilation.
The T3 surface is bi-directional, so DBA43929S does not require separate left- and right-side part numbers.
