DBA DBA42309XS 4000 Series XS Drilled and Slotted Brake Rotor with Gold Finish

The DBA 4000 Series XS Gold rotor delivers premium performance with a non-directional cross-drilled and slotted design, plus an attractive gold finish on the rotor hub. This direct replacement single-piece brake rotor is designed for drivers seeking upgraded performance braking above and beyond standard OE levels.

Key Features:

• Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), the metallurgy can handle increased stress and heat generated under intense braking applications
• Kangaroo Paw ventilation implements 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
• Unique cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in better braking performance
• Symmetrical slots and chamfered drill holes facilitate friction dust and gas exit for quieter, more responsive pedal feel
• Painted non-friction areas prevent rust and enhance appearance
• Thermographic heat paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Symmetrical slotting and drilling for universal left/right use

The XS version is recommended for high-performance street use. While providing similar performance benefits to the T3 slot, the XS Gold is a popular alternative for show cars.
