DBA DBA42443XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 42443XS is a high-performance 4000 Series XS brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This premium rotor features a non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub, combining superior function with show-quality appearance.

Advanced Cooling Technology:

• Kangaroo Paw ventilation system 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 holes and slots increase 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

Premium Materials and Construction:

• Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat from intense braking applications
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear
• Painted non-friction areas prevent rust and enhance appearance
• Symmetrical slotting and drilling for universal left/right use

Performance Monitoring:

• Thermo-Graphic Heat Paint changes color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

While providing similar performance benefits to the T3 slot design, the XS Gold is a popular alternative for show cars. The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. This direct replacement single-piece rotor delivers enhanced stopping power, improved pedal feel, and distinctive styling for enthusiasts who demand both performance and appearance.
