DBA DBA42219XS 4000 Series XS Drilled and Slotted Disc Brake Rotor

The DBA 4000 Series XS (DBA42219XS) is a premium performance disc brake rotor engineered as a direct OE replacement for drivers who demand braking capability beyond standard factory levels. Featuring a non-directional cross-drilled and slotted surface design, this rotor delivers superior heat dissipation and consistent stopping power for high-performance street driving.

Key Features:

• XS Cross-Drilled & Slotted Design: Non-directional pattern increases exit points for brake pad friction dust and gases, resulting in cleaner, more consistent braking performance and reduced brake fade
• Kangaroo Paw Ventilation: DBA's patented internal vane design features 144 diamond and teardrop-shaped pillars, delivering up to 30% more surface area and up to 20% improvement in cooling efficiency over conventional straight-vane rotors
• XG-150 High Carbon Alloy Iron Construction: Cast from premium high-carbon alloyed iron for exceptional strength, durability, and thermal stability under demanding braking conditions
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process subjects the rotor to controlled heat cycles to relieve internal manufacturing stresses, ensuring maximum dimensional stability and reduced metal fatigue in high-demand applications
• Temperature Heat Paint Markings: Color-changing paint indicators on non-friction surfaces change at specific temperature thresholds, allowing drivers to monitor peak braking temperatures and rotor fatigue over time
• Universal Left/Right Fitment: Symmetrical slot and drill pattern eliminates the need for separate left and right rotors, simplifying installation
• Corrosion-Resistant Finish: Non-friction surfaces are painted to prevent rust and enhance aesthetics straight out of the box

The 4000 Series XS is ideally suited for spirited street driving and high-performance daily use. While not intended for dedicated motorsports or heavy off-road applications, it offers a significant upgrade over stock rotors in demanding real-world conditions. Sold individually.
