DBA DBA42605BLKXS Series XS Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series XS Cross-Drilled and Slotted Brake Rotor is a premium direct replacement single-piece performance rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. Featuring DBA's advanced materials and engineering, this rotor delivers exceptional heat management and consistent braking power under demanding driving conditions.

Advanced Construction and Materials:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) process relieves internal stresses and optimizes metallurgy to handle extreme heat and stress
• 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
• Black hub finish provides corrosion resistance and enhanced aesthetics

XS Cross-Drilled and Slotted Design:

• Non-directional cross-drilled holes and slots increase the number of exit points for brake pad friction dust and gases
• Improves braking consistency and pedal feel by evacuating gases and debris more effectively
• Symmetrical design allows for universal left/right installation
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation

Performance Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Enhanced heat dissipation extends brake component life and maintains braking effectiveness
• Painted non-friction areas prevent rust and enhance appearance
• Direct bolt-on replacement requiring no modifications

The DBA 4000 Series XS rotor combines performance, durability, and visual appeal, making it an ideal choice for performance street driving and spirited driving applications where superior braking is essential.
