DBA DBA4718XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series is a direct replacement single-piece performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. The XS Gold variant features a premium non-directional cross-drilled and slotted design that increases exit points for brake pad friction dust and gases, plus an attractive gold finish on the rotor hub.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP) to handle increased stress and heat during intense braking applications
• Features patented Kangaroo Paw ventilation with 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and potential for premature wear
• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to assist with monitoring braking temperatures

Performance Benefits:

• Cross-drilled holes and slots work together to evacuate friction dust and gases for consistent braking performance
• Symmetrical design facilitates friction dust and gas exit for quieter and more responsive pedal feel
• Universal left/right design for simplified installation
• Painted non-friction areas prevent rust and enhance appearance

While providing similar performance benefits to the T3 slotted design, the XS Gold is a popular alternative for show cars. Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage.
