DBA DBA42011XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS features a premium non-directional cross-drilled and slotted design engineered for drivers seeking upgraded braking performance beyond standard OE levels. Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling, DBA's metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.

Advanced Cooling Technology:

• Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 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 to escape, resulting in better braking performance
• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gasses for a quieter and more responsive pedal feel

Performance Features:

• 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 for universal left/right use
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear

This direct replacement single-piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels. The XS version is not recommended for motorsports usage, but is more than capable for high performance street use.
