DBA DBA4092XS Series XS Cross-Drilled Slotted Brake Rotor - 4000

The DBA DBA4092XS is a high-performance disc brake rotor from the 4000 Series XS lineup, engineered for drivers seeking upgraded braking performance beyond standard OE levels. This direct replacement rotor features a premium cross-drilled and slotted design with an attractive gold-painted hub that resists corrosion while enhancing aesthetics behind custom wheels.

Advanced Metallurgy and Heat Treatment:

• Cast from XG-150 high-carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) process subjects rotors to controlled heat cycles, relieving internal stresses and maximizing thermal stability
• Enhanced capacity to handle constant extreme heat over prolonged periods without warping or fade

Patented Kangaroo Paw Ventilation Technology:

• Features 144 diamond and teardrop-patterned pillars for optimal cooling
• Delivers up to 30% increase in surface area compared to traditional straight vane designs
• Provides up to 20% improvement in cooling efficiency for consistent braking performance

Cross-Drilled and Slotted Design:

• Non-directional cross-drilled holes and slots create multiple exit points for brake dust, gases, and water
• Bi-directional symmetrical pattern allows universal left/right installation
• Chamfered drill holes facilitate smoother, quieter pedal feel with improved response
• Gold-painted non-friction surfaces prevent rust and deliver show-quality appearance

Thermo-Graphic Heat Paint (TGHP):

• Temperature-sensitive paint stripes change color at specific heat thresholds
• Allows drivers to monitor peak rotor temperatures and adjust driving style or pad selection accordingly

The DBA 4000 Series XS rotor is ideal for high-performance street applications where both aggressive braking capability and visual appeal are priorities. While not recommended for heavy track use or severe off-road conditions due to the cross-drilled design, this rotor excels in spirited street driving and delivers significantly improved heat management over stock rotors.
