DBA DBA42049XS Series Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series XS brake rotor is a direct replacement single-piece performance rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor can handle the increased stress and heat generated under intense braking applications.

Key Features:

• Premium non-directional cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in improved braking performance
• Patented 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
• Attractive gold finish on the rotor hub for enhanced aesthetics
• Thermal Stability Profiling (TSP) process subjects XG-150 grey iron to prolonged heat cycles under controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue
• Symmetrical slotting and drilling allows for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS version is ideal for high-performance street use, though not recommended for motorsports usage. Thermo-Graphic heat paint markings change color at specific temperatures for easy monitoring of rotor heat levels.
