DBA DBA42325XS Series Cross-Drilled Slotted Uni-Directional Brake Rotor - 4000

The DBA DBA42325XS 4000 Series is a high-performance cross-drilled and slotted brake rotor engineered for drivers who demand consistent, reliable stopping power under demanding conditions. Built by Disc Brakes Australia — a trusted name in performance braking — this uni-directional rotor is designed to handle repeated extreme heat cycles without sacrificing performance or pedal feel.

At the core of the DBA 4000 Series is XG-150 High Carbon Alloyed Iron, a proprietary metallurgy that delivers superior thermal capacity and improved structural integrity compared to standard grey iron rotors. This alloy is paired with DBA's exclusive Thermal Stability Profiling (TSP) technology, which optimizes the rotor's mass distribution to better absorb and dissipate heat during aggressive, late-braking scenarios.

Key Features:

• Cross-Drilled & Slotted Design: Holes evacuate heat, gas, and dust while slots continuously sweep the brake pad surface for consistent bite and improved wet-weather performance
• XG-150 High Carbon Alloyed Iron: Premium alloy formula for enhanced thermal capacity and reduced risk of heat cracking
• Thermal Stability Profiling (TSP): Engineered mass distribution for stable, predictable performance through repeated hard braking events
• Uni-Directional Configuration: Optimized rotor geometry for consistent airflow and cooling performance
• OEM-Style Fitment: Direct bolt-on replacement with no modification required
• Corrosion-Resistant Finish: Zinc-washed coating on non-swept surfaces helps prevent rust during storage and initial use

The DBA 4000 Series is the ideal upgrade for performance-minded drivers looking for a rotor that goes beyond the factory replacement. Whether on the track, tow vehicle, or spirited street use, the DBA42325XS delivers the thermal management and rotor longevity needed to perform lap after lap or stop after stop.
