Product Description

The DBA 42990S 4000 Series T3 Slotted Front Brake Rotor is engineered as a high-performance replacement rotor for select Chevrolet Corvette C6 and Cadillac XLR models. Designed with DBA's patented Tri-symmetrical (T3) slot pattern and Kangaroo Paw ventilation system, this rotor helps dissipate heat more efficiently and evacuates brake dust and gases to deliver a smoother, more responsive braking feel compared to standard OEM rotors.

Ideal for street driving, spirited performance use, or occasional track days, the DBA42990S brings upgraded stopping power and improved fade resistance while retaining direct fitment and ease of installation. Built from high carbon iron and precision machined to exacting tolerances, this rotor improves thermal stability and durability over typical stock rotors. Whether you're maintaining everyday braking performance or seeking enhanced control under demanding conditions, the 4000 Series T3 rotor is a solid upgrade for vehicles within its verified fitment range.
