DBA DBA42524XS 4000 Series Drilled and Slotted Brake Rotor

The DBA 4000 Series XS rotor delivers enhanced braking performance with a premium cross-drilled and slotted design engineered for high-performance street applications. Cast from XG-150 high carbon alloyed iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) process, this rotor is built to withstand the intense stress and heat generated during aggressive braking.

Key Features:

• Cross-drilled and slotted surface design increases exit points for brake pad friction dust and gases, improving braking consistency and pedal response
• Kangaroo Paw ventilation design with 144 diamond and teardrop-patterned pillars provides up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermal Stability Profiling heat treatment realigns the iron microstructure for increased rotor stability and durability
• Thermographic heat paint markings change color at specific temperature thresholds to help monitor braking temperatures and rotor fatigue
• Symmetrical drilling and slotting allows universal left/right installation
• Painted non-friction areas prevent rust and enhance appearance with attractive gold hub finish
• Centre-split core castings maximize heat transfer and thermal efficiency

The 4000 Series XS provides an excellent balance of performance and aesthetics for drivers seeking upgraded braking capability above OE levels. While suitable for spirited street driving, this drilled/slotted configuration is not recommended for heavy track day or motorsports usage.
