DBA DBA4660XS 4000 Series XS Gold Cross-Drilled and Slotted Front Brake Rotor

The DBA DBA4660XS is a premium performance brake rotor from the 4000 Series XS Gold line, designed as a direct replacement upgrade for drivers seeking enhanced braking performance beyond OE levels. This front brake rotor features a distinctive gold finish on the rotor hub combined with a non-directional cross-drilled and slotted design, making it an ideal choice for both performance enthusiasts and show car applications.

Advanced Thermal Technology:

• Cast from XG-150 high carbon alloyed iron for exceptional strength and durability
• Thermal Stability Profiling (TSP) treatment subjects the rotor to controlled heat cycles, relieving internal stresses and maximizing thermal stability
• Kangaroo Paw ventilation design features 144 diamond and teardrop patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Thermo-Graphic Heat Paint markings change color at specific temperature thresholds to help monitor braking temperatures and rotor fatigue

Performance Features:

• Cross-drilled and slotted pattern increases exit points for brake pad friction dust and gases, resulting in improved braking performance and pedal feel
• 290mm rotor diameter for optimal braking surface area
• Symmetrical drilling and slotting design allows universal left/right installation
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and potential for premature pad wear
• Painted non-friction areas prevent rust and enhance appearance

Important Note: While the XS Gold rotor provides similar performance benefits to DBA's T3 slotted design, drilled rotor configurations are not recommended for heavy off-road or dedicated track day usage due to the reduced structural integrity from the cross-drilled holes. This rotor is sold individually, with 2 required per vehicle for front axle installation.
