DBA DBA4487XS Series Cross Drilled Slotted Brake Rotor - 4000

The DBA DBA4487XS is a high-performance direct replacement brake rotor from DBA's 4000 Series XS lineup, engineered for drivers seeking superior braking performance beyond OE specifications. This premium rotor features a non-directional cross-drilled and slotted design that enhances cooling and evacuates brake dust and gases for more consistent stopping power.

Advanced Metallurgy and Construction:

• Cast from XG-150 high carbon alloyed iron for superior heat resistance and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and increases structural stability
• Patented Kangaroo Paw ventilation design with 144 diamond and teardrop pillars provides up to 30% more surface area and 20% improved cooling efficiency compared to traditional straight vane designs
• Center-split core castings maximize heat transfer and thermal efficiency

Performance Features:

• Cross-drilled and slotted friction surface increases exit points for brake pad dust and gases
• Symmetrical drilling and slotting allows universal left/right installation
• Chamfered drill holes facilitate smoother gas evacuation for quieter, more responsive pedal feel
• Thermographic heat paint markings change color at specific temperatures to monitor rotor performance and help with pad selection
• Painted non-friction areas prevent rust and enhance appearance behind wheels

The 4000 Series XS combines race-inspired technology with street-friendly characteristics, making it ideal for performance street driving and spirited weekend drives. Note that cross-drilled configurations are not recommended for heavy track day or off-road use.
