DBA DBA4093XS Series XS Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. The XS Gold variant features a premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. This rotor is ideal for high-performance street use, though not recommended for motorsports applications.

Advanced Cooling Technology:

• Kangaroo Paw ventilation 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
• Cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• Symmetrical slots and chamfered drill holes facilitate debris exit for a quieter and more responsive pedal feel

Premium Metallurgy and Construction:

• Cast from high-carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat from intense braking applications
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
• Center-split core castings for increased heat transfer and thermal efficiency
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue

Installation and Compatibility Features:

• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas to prevent rust and enhance appearance
• Direct bolt-on replacement for factory rotors

The DBA 4000 Series XS rotor combines race-proven technology with street-friendly characteristics, delivering consistent stopping power, improved heat dissipation, and extended service life for performance-minded drivers.
