DBA DBA4569XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA DBA4569XS is a high-performance 4000 Series XS disc brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This direct replacement single-piece rotor combines premium materials with advanced engineering for superior stopping power and heat management.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for exceptional durability
• Thermal Stability Profiling (TSP) heat treatment process reduces internal stress and metal fatigue
• Cross-drilled and slotted rotor face efficiently vents friction gases, water, and debris
• Symmetrical design allows for universal left/right installation

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars for superior cooling
• Provides up to 30% increase in surface area compared to traditional straight vane designs
• Delivers 20% improvement in cooling efficiency to minimize brake fade
• Enhanced heat dissipation prolongs brake life and maintains consistent performance

Performance Features:

• Gold-painted non-friction surfaces prevent rust and enhance appearance
• Thermo-Graphic heat paint indicators change color to monitor rotor temperatures
• Quieter, more responsive pedal feel with reduced brake dust buildup
• Ideal for high-performance street driving applications

The XS variant's cross-drilled and slotted pattern increases exit points for brake pad friction dust and gases, resulting in better braking consistency and performance. Note that drilled rotor configurations are not recommended for heavy off-road or track day usage, but excel in spirited street driving conditions.
