DBA DBA4788XS Series Cross-Drilled Slotted Performance Brake Rotor - 4000

The DBA 4000 Series is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. The 4000XS features a premium cross-drilled and slotted pattern that works in conjunction with DBA's patented Kangaroo Paw ventilation system. The XS pattern increases the number of out-gassing exit points to allow brake pad friction gases to escape, which increases the consistency and effectiveness of every brake stop.

Advanced Materials and Heat Management:

• Cast from XG-150 high carbon alloyed iron and undergoes Thermal Stability Profiling (TSP) for prolonged rotor service life
• Features Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Metallurgy can handle increased stress and heat generated under intense braking applications

Performance Features:

• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas to prevent rust and enhance appearance
• Ideal for high-performance street use

Thermal Stability Profiling (TSP) subjects XG-150 grey iron to prolonged heat cycles under controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue in extremely demanding applications.
