DBA DBA4996XS Series Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series XS rotor features a premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. This direct replacement single-piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat during intense braking
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation

Performance Features:

• Cross-drilled holes and slots increase exit points for brake pad friction dust and gases, resulting in better braking performance
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures
• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gasses for a quieter and more responsive pedal feel
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. Drilled rotor configurations are not recommended for heavy off-road or track day usage.
