DBA DBA53146BLKXD 5000 Series XD 2-Piece Cross-Drilled Dimpled Black Hat Brake Rotor with Kangaroo Paw Vanes

The DBA DBA53146BLKXD is a fully assembled 5000 Series XD two-piece performance brake rotor featuring a black anodized aluminum hat and a non-directional cross-drilled and dimpled cast iron rotor ring. Engineered for high-performance street driving and spirited use, this rotor delivers a significant upgrade over OEM braking components.

5000 Series XD Design:

• Cross-Drilled & Dimpled (XD) Surface: Combines drilled holes and dimples in a non-directional pattern for improved heat dissipation and enhanced sports aesthetics. The XD design provides enhanced structural support compared to traditional cross-drilled-only techniques.
• Aluma-Lite Black Anodized Hat: Two-piece center hat constructed from extra lightweight 6061-T6 aircraft-grade aluminum, reducing unsprung weight for better vehicle handling and minimizing heat transfer to the wheel hub. Black anodized finish resists rust and corrosion.
• Kangaroo Paw Vane Technology: Unique vein design provides up to 20% better heat dissipation compared to conventional vented rotors, increasing braking effectiveness and prolonging brake life.
• Thermal Stability Profiling (TSP): Heat treatment cycles realign the microstructure of the cast iron ring, resulting in increased rotor stability and durability under sustained braking loads.
• CBN Machine Turned Finish: Cubic Boron Nitride machining minimizes disc thickness variation, reducing the potential for pad knock and premature wear.
• Bi-Directional Use: Symmetrical drilling pattern allows universal fitment on either the left or right side.
• Thermographic Heat Paint: Paint markings change color at specific temperature thresholds to help monitor rotor temperatures and fatigue levels.
• Fully Assembled: Sold as a complete assembly with hat and disc ring bolted together, ready for direct installation.

The DBA 5000 Series is recommended for high-performance street vehicles, track day and club racing, rally applications, and show vehicles. The two-piece design allows for future cost savings — when the disc ring wears, only the ring needs to be replaced, reusing the original aluminum hat.
