DBA DBA42961XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series XS brake rotor delivers upgraded performance braking for drivers seeking superior stopping power beyond standard OE levels. This premium cross-drilled and slotted rotor features an attractive gold finish on the rotor hub, combining enhanced performance with show-quality aesthetics.

Key Features:

• Cross-drilled and slotted design provides multiple exit points for brake pad friction dust and gases, resulting in improved braking performance and more consistent pedal feel
• Cast from XG-150 high carbon alloyed iron with Thermal Stability Profiling (TSP) to handle increased stress and heat from intense braking applications
• Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and reduces potential for pad knock and premature wear
• Centre-split core castings for increased heat transfer and thermal efficiency
• Painted non-friction areas prevent rust and enhance appearance
• Symmetrical drilling and slotting allows universal left/right use
• Suitable for high performance street use

DBA's proprietary Thermal Stability Profiling subjects the rotor to prolonged heat cycles under strictly controlled conditions to relieve internal stresses from manufacturing, ensuring maximum thermal stability and reduced metal fatigue in demanding applications.
