DBA DBA42993XS 4000 Series XS Cross-Drilled and Slotted Rear Vented Brake Rotor

The DBA DBA42993XS is a premium 4000 Series XS performance brake rotor designed as a direct replacement for drivers seeking enhanced braking performance beyond OE levels. This rear vented disc rotor features DBA's signature cross-drilled and slotted design, providing superior friction management and heat dissipation for improved stopping power.

Advanced Metallurgy and Heat Management:

• Cast from high carbon alloyed iron with Thermal Stability Profiling (TSP) for superior heat resistance
• Kangaroo Paw ventilation design with 144 diamond and teardrop pillars delivers up to 20% better heat dissipation
• 30% increase in cooling surface area compared to traditional straight vane designs
• Enhanced capacity to handle sustained extreme heat loads during aggressive braking

Performance Features:

• Cross-drilled and slotted design provides multiple exit points for brake dust, gases, and moisture
• Non-directional pattern allows universal left/right installation
• CBN (Cubic Boron Nitride) machined friction surface minimizes disc thickness variation and pad knock
• Thermographic paint markings change color at specific temperatures to assist with brake monitoring
• Painted non-friction surfaces prevent rust and enhance appearance

The XS configuration delivers quieter operation, more responsive pedal feel, and improved braking consistency. Ideal for performance street driving and spirited use, this rotor combines advanced engineering with proven durability. Note: Cross-drilled configurations are not recommended for heavy track day or extreme off-road usage.
