The DBA 4000 Series T3 Front Brake Rotors, part number DBA42994S, are direct-replacement performance rotors for 1997–2004 C5 Corvette models, including the 2001–2004 Z06.

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 C5 Corvette front brake configuration while adding DBA’s performance-focused rotor material, slot pattern, ventilation, and heat-management features.
The T3 slots continuously pass across the brake-pad surface to help maintain consistent pad contact during repeated braking. Because the slot pattern is bi-directional, DBA42994S does not require separate left- and right-side part numbers.

The DBA42994S rotors install in the factory C5 Corvette front rotor locations and work with the original front calipers and mounting brackets. No caliper relocation brackets, rotor adapters, or changes to the factory rotor diameter are required.
Both rotors should be installed together. Clean the rotor and hub mounting surfaces before installation, inspect the brake pads and caliper hardware, and follow the DBA and brake-pad manufacturer bedding procedures after installation.
