DBA DBA4538XS 4000 Series XS Gold Drilled and Slotted Brake Rotor

The DBA 4000 Series XS Gold Brake Rotor combines high-performance braking with distinctive styling, featuring a premium non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. This direct replacement single-piece rotor is engineered for drivers seeking upgraded braking performance beyond standard OE levels while maintaining show-quality aesthetics.

Advanced Thermal Management:

• Cast from XG-150 high carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment process eliminates internal stresses and maximizes thermal stability
• Kangaroo Paw ventilation design with 144 diamond and teardrop-shaped pillars provides 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 monitor braking temperatures and rotor fatigue

Performance Features:

• Cross-drilled and slotted surface design creates multiple exit points for brake pad friction dust and gases, resulting in improved braking performance and more responsive pedal feel
• Non-directional drilling pattern allows for universal left/right use, simplifying installation
• Painted non-friction areas prevent rust and enhance appearance with gold hub finish
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation

The XS Gold variant offers similar performance benefits to the T3 slot design while providing a popular alternative for show cars and enthusiasts who want both performance and style. Note that drilled rotor configurations are not recommended for heavy off-road or track day usage. This rotor has a 255mm diameter and is designed for front axle applications, with 2 rotors required per vehicle.
