DBA DBA4200XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA DBA4200XS is a high-performance direct replacement brake rotor from DBA's 4000 Series XS line, designed for drivers seeking upgraded braking performance beyond standard OE levels. This rotor features a premium cross-drilled and slotted design that maximizes friction material evacuation and heat dissipation for enhanced stopping power.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process reduces internal stresses and metal fatigue
• Kangaroo Paw ventilation design with 144 diamond and teardrop pillars provides up to 30% more surface area and 20% better 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 evacuates brake dust, gases, and moisture for consistent pedal feel and quieter operation
• Symmetrical drilling and slotting pattern allows for universal left/right fitment
• Thermo-Graphic Heat Paint (TGHP) temperature monitoring stripes change color at critical temperature thresholds to help drivers monitor braking performance
• Painted non-friction areas prevent corrosion and enhance appearance
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation

The DBA 4000 Series XS rotor is ideal for high-performance street driving and spirited enthusiasts who want both improved braking performance and aggressive styling. Note that cross-drilled rotors are not recommended for heavy track use or motorsports applications.
