DBA DBA4910XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA DBA4910XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. Part of the 4000 Series XS Gold line, this rotor features a premium non-directional cross-drilled and slotted design that increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the drilled holes and slots for better braking performance.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), the metallurgy handles increased stress and heat under intense braking applications
• Features DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency
• TSP process subjects the iron to prolonged heat cycles under controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue in high-demand applications

Key Features:

• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for a quieter and more responsive pedal feel
• Painted non-friction areas prevent rust and enhance appearance; symmetrical design allows universal left/right use
• Thermographic heat paint markings change color at specific temperatures to monitor rotor performance
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage. This rotor provides an excellent balance of performance and aesthetics for enthusiast street applications.
