DBA DBA42304XS Series Cross-Drilled Slotted Performance Brake Rotor - 4000

The DBA DBA42304XS is a high-performance brake rotor from the 4000 Series XS lineup, engineered for drivers seeking upgraded braking performance beyond OE standards. This direct replacement single-piece rotor combines advanced metallurgy with precision manufacturing for exceptional heat management and consistent stopping power.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) process relieves internal stresses and maximizes thermal stability
• Patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars
• Achieves up to 30% increase in surface area and 20% improvement in cooling efficiency versus traditional straight vane designs
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation

XS Cross-Drilled and Slotted Design:

• Non-directional cross-drilled and slotted pattern for universal left/right application
• Chamfered drill holes and symmetrical slots facilitate rapid exit of friction dust and gases
• Delivers quieter operation and more responsive, smoother brake pedal feel
• Gold-painted non-friction areas prevent rust and enhance appearance
• Ideal for street performance and show vehicles

Performance Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to monitor peak rotor temperatures
• Enhanced brake pad bite and consistent stopping performance
• Reduced metal fatigue in high-demand braking applications
• Direct bolt-on replacement with no modifications required

Note: Cross-drilled rotor configurations are not recommended for heavy off-road or track day usage. Sold individually.
