Chevrolet Cobalt Brake Rotor (1) - Front - DBA - 4000 Series HD - `05-`08. A direct-fit front replacement rotor engineered for drivers who want DBA performance with an OE-style finish for 2005–2008 Chevrolet Cobalt models equipped with single-piston calipers.

This DBA 4000 Series HD rotor is cast from XG-150 high carbon alloyed iron and undergoes DBA’s Thermal Stability Profiling (TSP) to reduce the risk of distortion under repeated heavy braking. The rotor uses DBA’s patented Kangaroo Paw ventilation — 144 diamond and teardrop patterned pillars — to increase rotor surface area and improve cooling versus traditional straight vane designs. The 4000 Series HD keeps a smooth, plain OE-style face while providing improved heat management and consistent pad bedding for street or controlled-division track use. Rotors come with thermo-graphic paint markings (THGP) and moisture-proof corrosion protection packaging for storage and shipping.
