DBA DBA42526XS 4000 Series Cross-Drilled and Slotted Brake Rotor

The DBA DBA42526XS 4000 Series XS brake rotor features a premium non-directional cross-drilled and slotted design, engineered for drivers seeking upgraded braking performance beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), this rotor's metallurgy can handle the increased stress and heat generated under intense braking applications.

Advanced Cooling Technology:

• Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Cross-drilled holes and slots increase exit points for brake pad friction dust and gases, resulting in better braking performance
• Centre-split core castings for increased heat transfer and thermal efficiency

Performance Features:

• Symmetrical slots and chamfered drill holes facilitate the exit of friction dust and gases for quieter, more responsive pedal feel
• Symmetrical slotting and drilling for universal left/right use
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation
• 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

Thermal Stability Profiling (TSP) is a DBA proprietary process where XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions, ensuring maximum thermal stability and reduced metal fatigue in extremely high demanding applications. The XS version is ideal for high performance street use. This is a direct replacement single-piece brake rotor sold individually.
