DBA DBA42533XS Series Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series disc brake rotor is a direct replacement single-piece performance rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. The XS designation indicates this premium cross-drilled and slotted design with an attractive gold finish on the rotor hub.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor can handle the increased stress and heat generated under intense braking applications
• Features DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

Performance Features:

• Unique cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and reduces pad knock and premature wear
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage. This rotor provides an excellent balance of performance, aesthetics, and durability for street performance and occasional spirited driving applications.
