DBA DBA43341XD 4000 Series XD Cross-Drilled & Dimpled Rear Brake Rotor

The DBA DBA43341XD is a 4000 Series XD performance brake rotor engineered as a direct-fit, single-piece replacement for drivers seeking a meaningful upgrade over stock OE braking. Designed and manufactured by Disc Brakes Australia (DBA), this rotor delivers enhanced stopping power, superior heat management, and aggressive sport aesthetics.

XD Cross-Drilled & Dimpled Design:

The XD variant combines cross-drilled holes with strategically placed dimples across the rotor face. This unique mix provides enhanced rotor structural support compared to traditional cross-drilled-only designs, while delivering additional cooling performance above the standard HD specification. Chamfered drill holes help facilitate the exit of brake dust and gases, contributing to a quieter, more responsive pedal feel. Note: drilled rotor configurations are not recommended for heavy off-road or track day use.

Key Features:

• High Carbon Alloyed Iron Construction — Cast from premium XG-150 high carbon alloyed iron for superior resistance to warping, cracking, and wear under intense braking
• Thermal Stability Profiling (TSP) — DBA's proprietary heat treatment process relieves internal manufacturing stresses and optimizes the rotor's microstructure for maximum thermal stability and reduced metal fatigue
• Kangaroo Paw Ventilation — Patented internal vane design featuring 144 diamond and teardrop-shaped pillars, delivering up to 30% more surface area and 20% improved cooling efficiency versus traditional straight-vane rotors
• Thermo-Graphic Heat Paint (TGHP) — Color-coded paint markings (green, orange, red) change color at predetermined temperature thresholds, allowing drivers to monitor rotor temperatures and optimize pad selection
• Symmetrical Drilling — Non-directional design allows universal left/right fitment with no need to order separate driver/passenger-side rotors
• Rust-Inhibiting Paint — Non-friction areas are coated to prevent corrosion and maintain a clean, finished appearance

Sold individually. This rotor is ideal for performance street driving where improved brake feel, cooling, and appearance are priorities.
