DBA DBA4957XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA DBA4957XS is a direct replacement performance brake rotor from the acclaimed 4000 Series lineup, engineered for drivers seeking enhanced braking performance beyond OE levels. This single-piece rotor features DBA's premium XS (cross-drilled and slotted) design with an attractive gold-painted hub for both performance and show-quality aesthetics.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) process allows the rotor to handle increased stress and extreme heat under intense braking applications
• Patented Kangaroo Paw ventilation system 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
• Thermo-Graphic heat paint markings change color at specific temperatures, allowing drivers to monitor peak rotor temperatures

Performance Design Features:

• Non-directional cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in improved braking consistency and pedal feel
• Symmetrical drilling and slotting pattern allows universal left/right use
• Chamfered drill holes facilitate smooth gas evacuation for quieter, more responsive braking
• Gold protective coating on non-friction surfaces prevents rust and enhances appearance behind wheels

The 4000 Series XS rotor combines race-inspired performance with street-friendly durability, making it ideal for performance enthusiasts and show car applications. Note that drilled rotor configurations are not recommended for heavy off-road or track day usage where solid or T3 slotted variants would be more appropriate.
