DBA 05-12 Chevrolet Cobalt (5 Lug) Front 4000 Series Drilled & Slotted Rotor

The DBA 4000 Series XS Cross-Drilled/Slotted Brake Rotor is a premium direct replacement rotor designed for drivers seeking upgraded performance braking beyond standard OE levels. These rotors are cast from high carbon alloyed iron and undergo Thermal Stability Profiling (TSP), which allows the metallurgy to handle increased stress and heat generated under intense braking applications. They typically incorporate DBA's patented Kangaroo Paw ventilation system, which uses a series of 144 diamond and teardrop patterned pillars to achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. The XS cross-drilled and slotted pattern increases the number of out-gassing exit points, allowing brake pad friction gases to escape and increasing the consistency and effectiveness of every brake stop. DBA's universal drill and slot design eliminates the need for separate left and right slot designs. These rotors also feature thermographic temperature monitoring with heat paint markings that change color at specific temperature thresholds, providing a clear indication of peak braking temperatures. Non-friction areas are paint-protected to reduce corrosion and enhance appearance.
