DBA DBA42048XS Series Cross-Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series DBA42048XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor's advanced metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.

Key Features:

• Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars provides up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• XS Gold design features non-directional cross-drilled and slotted pattern with attractive gold finish on rotor hub
• Cross-drilled holes and slots increase exit points for brake pad friction dust and gases, resulting in better braking performance
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Painted non-friction areas prevent rust and enhance appearance
• Symmetrical slotting and drilling allows for universal left/right use

DBA 4000 XS Rotors are among the highest quality cross-drilled rotors on the market today. The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. This rotor is a direct replacement upgrade from original equipment brakes, featuring advanced materials, precision manufacturing, and DBA's patented Kangaroo Paw ventilation for cooler rotor temperatures.
