DBA DBA4963XS Series XS Cross-Drilled Slotted Brake Rotor - 4000

The DBA DBA4963XS is a premium direct-replacement performance brake rotor from the acclaimed 4000 Series XS lineup, designed for drivers seeking enhanced braking performance beyond OE levels. This single-piece vented rotor combines advanced materials and patented cooling technology to deliver superior stopping power for performance street cars, heavily laden vehicles, and towing applications.

Advanced Materials & Construction:

• Cast from high-carbon alloyed iron with XG150 alloy formulation for optimal heat resistance
• Thermal Stability Profiling (TSP) heat treatment realigns the iron's microstructure to handle extreme and prolonged heat
• Patented Kangaroo Paw ventilation design with 144 diamond and teardrop-patterned pillars increases cooling efficiency by up to 20%
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and premature pad wear

Performance Features:

• Non-directional cross-drilled and slotted XS design eliminates the need for different left and right discs
• Drill holes and slots provide multiple exit points for brake pad friction dust and gases, improving braking consistency
• Attractive gold finish on rotor hub adds visual appeal for show cars
• Thermographic heat paint markings change color at specific temperature thresholds to monitor peak braking temperatures and rotor fatigue
• Protective paint on all non-friction surfaces prevents corrosion and enhances appearance

Specifications:

• Outer Diameter: 296mm (11.65 inches)
• Disc Thickness: 30mm
• Minimum Thickness: 28mm
• Center Bore: 68mm
• Bolt Circle: 114.3mm (5-bolt pattern)
• Rotor Type: Vented, Cross-Drilled & Slotted

This rotor delivers the confidence and performance needed when you've exceeded your stock braking system's capabilities. The combination of advanced metallurgy, superior ventilation, and precision machining makes the DBA4963XS an ideal upgrade for demanding driving conditions.
