DBA DBA4915XS 4000 Series Drilled and Slotted Brake Rotor

The DBA DBA4915XS is a premium 4000 Series XS brake rotor featuring a cross-drilled and slotted design for enhanced performance braking. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor is engineered to handle the increased stress and heat generated under intense braking applications.

Key Features:

• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• Cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and reduces potential for pad knock and premature wear
• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures
• Painted non-friction areas to prevent rust and enhance appearance
• Symmetrical design for universal left/right use

This 4000 Series rotor is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. The 4000 XS Series is a popular alternative for open wheel and show cars, combining performance benefits with aggressive styling.
