DBA 4000 Series T3 Rear Slotted Brake Rotor for 2005-2011 Chevrolet Corvette & Cadillac XLR (DBA42991S)

Fits 2005-2011 Chevrolet Corvette and 2006-2009 Cadillac XLR (Select Base, Grand Sport, Z06, ZR1, and V models).

The DBA 4000 Series T3 is a high-performance, direct-replacement rear brake rotor designed for drivers who demand consistent stopping power and thermal stability. Engineered from XG-150 high-carbon alloyed iron, these rotors undergo a thermal stress-relieving process to handle the extreme heat cycles common in spirited driving and track applications. The patented Kangaroo Paw ventilation system features 144 precisely positioned pillars that increase surface area and air turbulence, providing significantly better cooling than traditional straight-vane designs.

These rotors utilize the T3 Tri-Symmetrical slot design, which effectively clears dust and gases while maintaining a quiet, smooth pedal feel. Each rotor is finished with a protective coating on the non-friction areas and includes thermographic heat paint markings to help you monitor peak braking temperatures. This is a single rear rotor (DBA42991S).
