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 C7 Corvette Stingray front calipers and mounting points while adding DBA’s T3 slot pattern, high-carbon iron construction, and performance-focused heat-management features.
C7 Corvette Stingray models use two different front rotor sizes. Stingrays with standard RPO JL9 brakes use 321 mm rotors, while Z51 Stingrays with RPO J55 performance brakes use larger 345 mm rotors. Check the Corvette’s brake RPO code before selecting a variant.
