DBA DBA4954XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA DBA4954XS is a high-performance single-piece disc brake rotor from DBA's 4000 Series XS line, engineered for drivers seeking upgraded braking performance beyond standard OE levels. This direct replacement rotor features a premium cross-drilled and slotted design that combines aggressive aesthetics with enhanced functionality.

Advanced Material and Heat Management:

• Cast from high-carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment realigns the iron microstructure to handle extreme stress and heat from intense braking applications
• Kangaroo Paw ventilation design features 144 diamond and teardrop patterned pillars, delivering up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Centre-split core castings maximize heat transfer and thermal efficiency

Performance Features:

• Cross-drilled and slotted surface design increases exit points for brake pad friction dust and gases, improving pedal feel and braking consistency
• Chamfered drill holes and symmetrical slots provide quieter operation and more responsive pedal feedback
• Non-directional design allows universal left/right fitment
• Thermo-Graphic heat paint markings change color at specific temperature thresholds for real-time monitoring of rotor temperatures
• Painted non-friction areas prevent rust and enhance appearance
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation

The XS variant is optimized for high-performance street use and light track applications. While not recommended for heavy motorsports or severe off-road use, the 4000 Series XS provides excellent stopping power, fade resistance, and heat dissipation for aggressive street driving conditions and vehicles with larger, heavier wheels.
