DBA DBA42246XS 4000 Series Cross-Drilled and Slotted Performance Brake Rotor

The DBA 4000 Series XS is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.

Key Features:

• 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
• Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine turned finish, minimizing disc thickness variation and the potential for pad knock
• Symmetrical slotting and drilling for universal left/right use
• Painted non-friction areas to 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 front vented disc brake rotor provides superior heat dissipation and consistent braking performance for enthusiast drivers who demand more from their braking system.
