DBA DBA42808WXD Series Cross-Drilled Slotted Wave Brake Rotor - 4000

The DBA DBA42808WXD 4000 Series Wave Brake Disc is a high-performance replacement brake rotor engineered for drivers seeking improved braking performance over a standard OEM rotor. Part of DBA's (Disc Brakes Australia) popular 4000 Series lineup, this rotor combines cross-drilled holes and directional slots with DBA's signature Wave-shaped rotor edge profile to maximize braking efficiency, heat dissipation, and rotor longevity.

Key Features:

• 4000 Series WXD Design: Features both cross-drilling (X) and directional slotting (D) across a wave-edge rotor for optimized bite and fade resistance
• Wave Rotor Technology: DBA's patented wave rotor profile reduces rotor mass and inertia at the outer edge, improving pad sweep and reducing heat buildup
• Cross-Drilled Holes: Improve outgassing under heavy braking and help expel gas, dust, and debris from the pad-rotor interface
• Directional Slots: Continuously clean and deglaze brake pad surface for consistent, fade-resistant stopping power
• Premium Metallurgy: Manufactured from high-quality grey iron to OEM or better specifications for durability and consistent performance
• Corrosion-Resistant Finish: Zinc-washed coating on non-braking surfaces helps resist rust and corrosion during storage and daily use
• Direct OEM Replacement: Bolt-on fitment with no modifications required
• Street and Track Capable: Suitable for performance street driving and light track use
