DBA DBA42537BLKXS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series XS brake rotor is a premium single-piece performance brake disc designed for drivers seeking upgraded braking performance above standard OE levels. Featuring a non-directional cross-drilled and slotted design with an attractive black finished hub, this rotor delivers enhanced braking while providing a high-performance aesthetic.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes material structure
• Enhanced fatigue resistance minimizes surface cracking during extreme use
• Engineered to handle intense braking applications repeatedly without degradation

Patented Kangaroo Paw Ventilation:

• 144 diamond and teardrop-patterned pillars between rotor faces
• Up to 30% increase in cooling surface area compared to conventional straight vane designs
• 20% improvement in cooling efficiency for better heat dissipation
• Provides additional support to friction surfaces for improved stability under high temperatures

Cross-Drilled and Slotted Design:

• Non-directional pattern allows single rotor to be used on either side
• Multiple exit points for brake pad friction dust and gases to escape
• Improved pad bite and more consistent braking performance
• Premium appearance with performance benefits

Thermo-Graphic Heat Paint (TGHP):

• Color-changing paint stripes monitor rotor temperature thresholds
• Green, orange, and red indicators change color at critical temperatures
• Helps drivers optimize pad selection and understand braking system performance

The 4000 Series XS is ideal for high-performance street applications where drivers want the visual appeal of cross-drilling combined with DBA's advanced rotor technology. While not recommended for dedicated motorsports use, these rotors are more than capable for spirited street driving and deliver significantly longer service life than conventional rotors.
