DBA DBA42552XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS brake rotor is a direct replacement performance upgrade designed for drivers seeking enhanced braking capabilities beyond standard OE levels. This rotor features a non-directional cross-drilled and slotted design that increases exit points for brake pad friction dust and gases, resulting in improved braking consistency and pedal feel.

Advanced Engineering Features:

• Cast from high carbon alloyed iron with Thermal Stability Profiling (TSP) for superior heat management and durability
• Kangaroo Paw ventilation design with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Symmetrical cross-drilled holes and slots for universal left/right fitment and optimal gas evacuation
• Thermographic heat paint markings that change color at specific temperature thresholds to monitor braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and reduces pad knock
• Centre-split core castings enhance heat transfer and thermal efficiency
• Painted non-friction areas prevent rust and enhance appearance

The XS variant provides excellent performance for high-performance street driving and is ideal for enthusiasts who demand both enhanced braking capabilities and attractive aesthetics. Not recommended for heavy motorsports or track day usage.
