DBA DBA42991XS 4000 Series Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS Gold rotor combines premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub, delivering enhanced braking performance for drivers seeking upgraded stopping power beyond standard OE levels. This direct replacement single-piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Advanced Metallurgy and Heat Management:

• 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
• Features DBA's Kangaroo Paw ventilation that 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
• Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue
• Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods

Premium Surface Design Features:

• The unique cross drilled and slotted design increases the number of exit points, allowing more brake pad friction dust and gases to escape through both the cross drilled holes and slots, 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
• Painted non friction areas to prevent rust and enhance appearance
• Symmetrical slotting and drilling for universal left/right use

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. This rotor represents an ideal balance of aggressive styling, enhanced heat dissipation, and improved braking consistency for performance-minded drivers.
