What to Expect

The DBA 4000 Series T3 is a factory-size, one-piece rear rotor upgrade rather than a big-brake conversion. It retains the original C7 Corvette Stingray rear calipers and mounting points while adding DBA’s T3 slot pattern, high-carbon iron construction, and performance-focused ventilation.

Unlike the front brake system, where JL9 and J55 Stingrays require different rotor sizes, both factory Stingray brake packages use the same DBA42761S rear rotor. The T3 pattern is bi-directional, so separate driver- and passenger-side part numbers are not required.
