DBA DBA4418XS 4000 Series Cross-Drilled and Slotted Front Brake Rotor

The DBA 4000 Series XS disc brake rotor is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. This premium rotor features a unique cross-drilled and slotted design that increases the number of exit points, allowing brake pad friction dust and gases to escape through both the drilled holes and slots for superior braking performance.

Advanced Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat generated under intense braking applications
• Features DBA's patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and potential for pad knock and premature wear

Premium XS Gold Finish:

• Features an attractive gold finish on the rotor hub for enhanced aesthetics
• Symmetrical slots and chamfered drill holes facilitate friction dust and gas exit for quieter and more responsive pedal feel
• Painted non-friction areas prevent rust and enhance appearance
• Symmetrical drilling allows for universal left/right use

Technical Specifications:

• Outer diameter: 320mm (12.6 inches)
• Thickness: 32mm with minimum thickness of 29.8mm
• Center hole: 69mm with 5 stud holes
• Vented rotor design for maximum heat dissipation

Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage. This rotor provides the ideal balance of performance, aesthetics, and heat management for enthusiast street driving and show vehicles.
