DBA DBA42010XS 4000 Series XS Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. The XS designation indicates this rotor features DBA's premium non-directional cross-drilled and slotted design, making it a popular alternative for show cars while delivering serious performance benefits.

Advanced Cooling Technology:

• 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
• Cross-drilled holes and slots increase exit points for brake pad friction dust and gases, resulting in better braking performance
• Symmetrical design facilitates the exit of friction dust and gases for a quieter and more responsive pedal feel

Premium Construction:

• Cast from high carbon alloyed iron and undergoes Thermal Stability Profiling to handle increased stress and heat generated under intense braking applications
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear
• Thermo-Graphic 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

Important Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage.
