DBA DBA42020XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS Drilled and Slotted Brake Rotor delivers premium performance braking technology for drivers seeking upgraded stopping power beyond standard OE levels. Engineered as a direct replacement single-piece rotor, this disc features XG-150 high carbon alloyed iron and Thermal Stability Profiling (TSP) technology for superior heat management and durability under demanding driving conditions.

Advanced Cooling Technology:

• 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
• Non-directional cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in improved braking performance
• TSP heat treatment process subjects rotors to controlled heat cycles that relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue in high-demand applications

Performance Features:

• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and potential for premature pad wear
• Thermo-Graphic Heat Paint (TGHP) temperature monitoring stripes change color at critical temperature thresholds to help monitor peak braking performance
• Bi-directional symmetrical design allows universal left/right installation
• Anti-rust coating on non-friction areas prevents corrosion and enhances appearance

The 4000 Series XS is engineered for high-performance street use and provides exceptional durability compared to standard rotors. This rotor combines race-proven technology with reliable everyday performance for enthusiasts who demand the best from their braking system.
