DBA DBA42996XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. The unique cross-drilled and slotted design increases the number of exit points, allowing brake pad friction dust and gases to escape through both the cross-drilled holes and slots, resulting in better braking performance.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy handles the increased stress and heat generated under intense braking applications.
• Features DBA's patented Kangaroo Paw ventilation that implements 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs.
• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue.

Premium XS Features:

• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel.
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and the potential for pad knock and resulting premature wear.
• Painted non-friction areas prevent rust and enhance appearance.
• Symmetrical slotting and drilling allows universal left/right use.

This premium performance brake rotor delivers superior heat dissipation, consistent braking performance, and an aggressive appearance for enthusiasts who demand more from their braking system.
