DBA DBA53910BLKXD Series XD Cross-Drilled Dimpled Brake Rotor Black Hat - 5000 2-Piece

The DBA DBA53910BLKXD is a fully assembled 5000 Series XD 2-piece performance brake rotor featuring a non-directional cross-drilled and dimpled surface with a black anodized aluminum hat. Engineered for high-performance street driving, track days, and club racing, this rotor delivers exceptional thermal management and braking consistency under demanding conditions.

5000 Series XD Design:

• Cross-Drilled & Dimpled (XD) Finish: Non-directional pattern combines drilled holes and dimples to provide enhanced structural support above traditional cross-drilled techniques, while improving cooling performance and aggressive sports aesthetics
• 2-Piece Composite Construction: High-carbon cast iron rotor ring paired with an aerospace-grade T6061-T6 aluminum hat, secured with National Aerospace Standards (NAS) bolts and crimp nuts for a precision, rattle-free assembly
• Kangaroo Paw Vane Technology: DBA's patented internal vane design — featuring 144 diamond and teardrop-shaped pillars — delivers up to 20% better heat dissipation compared to conventional straight-vane rotors, increasing braking effectiveness and prolonging rotor life
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process subjects the high-carbon iron to controlled heat cycles, relieving internal manufacturing stresses for maximum thermal stability and reduced metal fatigue during prolonged heavy braking
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint stripes (Green, Orange, Red) change color at specific temperature thresholds, allowing drivers to monitor peak rotor temperatures and optimize brake pad selection
• Reduced Unsprung Weight: The aluminum hat lowers unsprung mass, improving vehicle handling, acceleration, and deceleration response, while allowing uniform radial disc expansion and minimizing heat transfer from disc to hub
• Black Anodized Hat: Corrosion-resistant anodized finish on the aluminum hat enhances durability and visual appearance
• Bi-Directional / Universal Fitment: Symmetrical drilling and dimple pattern allows use on either left or right side

Sold individually. DBA recommends the 5000 Series for high-performance street vehicles, track day events, club racing, and rally applications where superior thermal management and reduced unsprung weight are critical.
