DBA DBA4926XS Series XS Cross-Drilled Slotted Performance Brake Rotor - 4000

The DBA 4000 Series XS rotor is a premium direct-replacement performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. Engineered for high-performance street use, this rotor combines advanced materials and innovative design features to deliver exceptional heat management and consistent stopping power.

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 realigns the metal's microstructure, reducing internal stress and increasing resistance to warping
• Enhanced thermal capacity handles constant extreme heat over prolonged periods

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop-patterned pillars between rotor faces
• Delivers up to 30% increase in surface area compared to traditional straight vane designs
• Provides up to 20% improvement in cooling efficiency for better heat dissipation
• Prolongs brake life and maintains consistent braking effectiveness

XS Cross-Drilled and Slotted Design:

• Non-directional cross-drilled and slotted pattern for universal left/right fitment
• Increases exit points for brake pad friction dust and gases to escape
• Results in quieter operation and more responsive pedal feel
• Chamfered drill holes reduce stress concentration points
• Gold-painted non-friction surfaces prevent rust and enhance appearance

Thermographic Heat Paint Markings:

• Temperature-sensitive paint changes color at specific heat thresholds
• Allows drivers to monitor peak braking temperatures and rotor fatigue
• Helps optimize brake pad selection based on driving style and conditions

Ideal for performance street vehicles, the DBA 4000 Series XS rotor provides the perfect balance of enhanced braking performance, thermal management, and aesthetic appeal. Manufactured to ISO 9001, QS 9000, TS 16949, and TUV certifications. Sold individually.
