DBA DBA42055XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. The XS variant features a premium non-directional cross-drilled and slotted design that increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross-drilled holes and slots, resulting in better braking performance.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again
• Features DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to a traditional straight vane design
• Thermal Stability Profiling (TSP) is a DBA proprietary process where XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions to relieve internal stresses from manufacturing, ensuring maximum thermal stability and reduced metal fatigue

Performance Features:

• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gasses for a quieter and more responsive pedal feel
• DBA's patented Thermo-Graphic Heat Paint (TGHP) markings are a standard feature on all DBA 4000 Series disc rotors
• Painted non-friction areas to prevent rust and enhance appearance
• Symmetrical slotting and drilling for universal left/right use

While providing similar performance benefits to the T3 slot, the XS is a popular alternative for show cars. Please note: Drilled rotor configurations are not recommended for heavy off-road or track day usage. Ideal for street performance applications, spirited driving, and enthusiasts seeking enhanced braking with an aggressive appearance.
