DBA DBA43162XS 4000 Series XS Drilled and Slotted Brake Rotor

The DBA 4000 Series XS is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. 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 drilled holes and slots, resulting in better braking performance.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) for increased stress and heat resistance
• XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions to relieve internal stresses, ensuring maximum thermal stability and reduced metal fatigue
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and potential for premature wear

Kangaroo Paw Ventilation Technology:

• Patented Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars
• Achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs

Thermo-Graphic Heat Paint (TGHP):

• TGHP paint stripes of Green, Orange and Red change color once the rotor reaches predetermined critical temperature thresholds
• Allows drivers to monitor peak rotor temperatures to better understand the effects of their driving style and make informed choices in pad selection

Performance Features:

• Slots and chamfered drill holes facilitate the exit of friction dust and gasses for a quieter and more responsive pedal feel
• Anti-rust 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 combines performance enhancement with an aggressive appearance, making it ideal for enthusiasts who demand both function and style.
