DBA DBA42994XS Series Drilled/Slotted Performance Brake Rotor - 4000

The DBA 4000 Series XS brake rotor delivers enhanced performance braking for drivers seeking capabilities beyond standard OE levels. This single-piece direct replacement rotor combines DBA's advanced metallurgy and patented cooling technology to handle demanding driving conditions with confidence.

Advanced Construction and Materials:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes thermal stability
• Patented Kangaroo Paw ventilation featuring 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

XS Design Features:

• Non-directional cross-drilled and slotted pattern for universal left/right application
• Cross-drilled holes and slots provide multiple exit points for brake pad friction dust and gases
• Delivers improved pedal response and more consistent brake performance
• Painted non-friction areas prevent rust and enhance appearance
• Thermographic Heat Paint indicators change color at specific temperature thresholds to monitor rotor temperatures

Performance Benefits:

• Designed for high-performance street use with significantly improved heat handling over OE rotors
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation
• Reduces brake fade during extended or aggressive braking
• Longer service life than most competitive rotors

Ideal for enthusiasts who want upgraded braking performance with the distinctive look of cross-drilled rotors. The DBA 4000 Series XS provides the perfect balance of performance, durability, and aesthetics for street-driven vehicles. Sold individually.
