DBA DBA4656XS 4000 Series Drilled and Slotted Brake Rotor

The DBA 4000 Series is a direct replacement single piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. The XS variant features a premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. The unique cross-drilled and slotted pattern 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 Materials and Construction:

• Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy can handle the increased stress and heat generated under intense braking applications
• Thermal Stability Profiling subjects XG-150 grey iron 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 the potential for pad knock and premature wear

Kangaroo Paw Ventilation Technology:

• 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 design
• Increases the rotor's capacity to handle constant and extreme heat over prolonged periods

Additional 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

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. Sold individually.
