DBA DBA42859XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This XS variant features a premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), the rotor's metallurgy can handle the increased stress and heat generated under intense braking applications.

Advanced Cooling Technology:

• 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 compared to traditional straight vane designs
• Cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• Centre-split core castings for increased heat transfer and thermal efficiency

Performance Features:

• Thermal Stability Profiling (TSP) heat treatment cycles relieve internal stresses from manufacturing, ensuring maximum thermal stability and reduced metal fatigue in high-demand applications
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and potential for pad knock and premature wear
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS version is ideal for high-performance street use and offers similar performance benefits to the T3 slot design while providing enhanced aesthetics with its gold hub finish. This rotor is sold individually and is designed for drivers demanding superior heat management and consistent braking performance in demanding driving conditions.
