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 C6 Corvette Z06 J56 rear calipers and mounting points while adding DBA’s T3 slot pattern, high-carbon iron construction, and performance-focused heat-management features.

The T3 slot pattern is bi-directional, so DBA42993S does not require separate driver- and passenger-side part numbers.

Install both rotors together, clean the rotor and hub mounting surfaces, inspect the brake pads and caliper hardware, and follow the DBA and brake-pad manufacturer bedding procedures after installation.

Why Buy DBA C6 Corvette Z06 Brake Rotors From Custom Corvette Accessories?

Custom Corvette Accessories is enthusiast owned and operated, so correct Corvette brake-package fitment and clear ordering information matter.
