DBA DBA4069XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA DBA4069XS is a high-performance single-piece brake rotor from the 4000 Series XS line, designed for drivers seeking upgraded braking performance beyond standard OE levels. This rotor features a cross-drilled and slotted surface design that enhances braking efficiency for high-performance street applications.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes material structure
• Enhanced capacity to handle constant and extreme heat over prolonged periods
• Significantly improved resistance to warping and thermal fatigue

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop patterned pillars between rotor faces
• Delivers up to 30% increase in cooling surface area
• Provides up to 20% improvement in cooling efficiency compared to traditional straight vane designs
• Centre-split core castings maximize heat transfer and thermal efficiency

Cross-Drilled and Slotted Design:

• Non-directional XS pattern with chamfered drill holes and symmetrical slots
• Multiple exit points for brake pad friction dust and gases
• Evacuates water and debris from rotor surface for consistent performance
• Universal left/right fitment eliminates need for side-specific rotors
• Delivers quieter operation and more responsive pedal feel

Additional Features:

• Thermo-Graphic heat paint markings change color at specific temperature thresholds for easy monitoring of brake temperatures
• Protective paint on non-friction areas prevents rust and enhances appearance
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Direct replacement design for bolt-on installation

The DBA 4000 Series XS rotor is ideal for enthusiasts who demand superior braking performance for spirited street driving. The cross-drilled and slotted configuration is recommended for high-performance street use but not for heavy motorsports or track day applications.
