DBA DBA42962XS 4000 Series XS Cross-Drilled and Slotted Brake Rotor

The DBA 4000 Series XS is a high-performance single-piece disc brake rotor engineered for drivers seeking superior braking performance beyond OEM standards. This premium rotor features a non-directional cross-drilled and slotted design that provides both enhanced performance and an aggressive appearance.

Advanced Materials and Construction:

• Cast from XG-150 high-carbon alloyed iron for exceptional strength and durability
• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes the metallurgy for extreme braking conditions
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-patterned pillars delivers up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight-vane designs
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and premature wear

Performance Features:

• Cross-drilled holes and precision slots work together to evacuate brake pad friction dust and gases for consistent pedal feel and improved stopping power
• Bi-directional design allows for universal left/right installation
• Thermographic Heat Paint markings change color at specific temperature thresholds to help monitor rotor temperatures and optimize pad selection
• Enhanced heat dissipation keeps rotors stable under heavy braking conditions
• Anti-rust painted non-friction areas prevent corrosion and enhance appearance

The 4000 Series XS rotor is ideal for high-performance street driving where both function and appearance matter. While not recommended for motorsports use, it delivers exceptional braking performance for spirited daily driving and provides significantly longer service life than standard rotors.
