DBA DBA42635XS Series XS Cross Drilled Slotted Brake Rotor - 4000

The DBA 4000 Series XS Gold rotor features a 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 OEM levels. This direct replacement single piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Advanced Materials and Engineering:

• Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling to handle increased stress and heat generated under intense braking applications
• Features DBA's Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear
• Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability

Performance Features:

• Unique cross drilled and slotted design increases exit points for brake pad friction dust and gases to escape, resulting in better braking performance
• Patented Thermo-Graphic Heat Paint (TGHP) markings change color at predetermined critical temperature thresholds, allowing drivers to monitor peak rotor temperatures
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. This rotor combines DBA's premium technology with the aggressive appearance of cross-drilled holes, making it ideal for enthusiasts seeking both performance and visual impact.
