DBA DBA42310XS Series XS Cross-Drilled Slotted Performance Brake Rotor - 4000

The DBA 4000 Series XS features a premium non-directional cross-drilled and slotted design engineered for drivers seeking upgraded performance braking beyond standard OE levels. The unique cross-drilled and slotted pattern increases the number of exit points, allowing brake pad friction dust and gases to escape through both the drilled holes and slots, delivering improved brake response and pedal feel.

Advanced Construction and Materials:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle extreme heat and stress during intense braking applications
• Features DBA's Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Symmetrical slotting and drilling for universal left/right use, eliminating the need for side-specific rotors
• Cubic Boron Nitride (CBN) machine turned finish minimizing disc thickness variation and premature wear

Performance Features:

• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Painted non-friction areas to prevent rust and enhance appearance
• Centre-split core castings for increased heat transfer and thermal efficiency
• Designed for high performance street use, providing enhanced stopping power for spirited driving

This single-piece direct replacement rotor delivers professional-grade braking performance with superior heat dissipation, making it an ideal upgrade for performance-oriented drivers who demand consistent, reliable stopping power.
