DBA DBA42830WSLVXD Series Wave XD Cross-Drilled Dimpled Brake Disc Rotor - 4000 340mm

The DBA DBA42830WSLVXD is a front 4000 Series Wave XD performance brake disc rotor measuring 340mm in diameter. Combining DBA's Wave profile with the XD cross-drilled and dimpled finish, this rotor delivers an advanced upgrade over standard OE brake components for performance-oriented street driving.

The Wave design is individually precision-milled on each rotor, drawing inspiration from the motorbike world to reduce overall rotor weight while increasing surface area for superior heat dispersal and maintained optimal brake pad temperatures. The scalloped outer edge also provides a distinctive, aggressive aesthetic.

The XD finish adds a non-directional pattern of cross-drilled holes and dimples across the rotor face, delivering additional cooling benefits over the standard 4000 HD spec. The unique combination of drilled holes and dimples also provides improved structural support compared to traditional fully cross-drilled designs.

Key Features:

• XG-150 High Carbon Alloyed Iron construction for superior strength and thermal capacity
• Thermal Stability Profiling (TSP) heat treatment aligns grain structure at the atomic level for uniform material composition and enhanced resistance to warping
• Kangaroo Paw Ventilation — 144 diamond and teardrop-shaped pillars deliver up to 30% more surface area and 20% improved cooling efficiency vs. straight vane designs
• Wave profile for reduced rotor weight and increased heat dispersal surface area
• Non-directional XD cross-drilled and dimpled finish for universal left/right fitment and enhanced cooling
• Thermographic Heat Paint Markings change color at specific temperature thresholds to monitor braking temperatures and rotor fatigue
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and reduces risk of pad knock and premature wear
• Painted non-friction areas to prevent rust and enhance appearance
• Direct OE replacement fitment — single piece design, sold individually (silver hat)
• OEM cross-reference: 1K0615301AD
• Minimum thickness: 28mm

Note: Drilled rotor configurations are not recommended for heavy off-road or track day usage. Recommended for performance street cars, performance SUVs, heavily laden vehicles, and towing applications.
