DBA DBA52396BLKCSL 5000 Series T3 Slotted 2-Piece Brake Rotor Black Hat

The DBA DBA52396BLKCSL is a 5000 Series T3 slotted, two-piece direct replacement brake rotor featuring a black anodized aluminum hat. Building on all the performance technology of the DBA 4000 Series, the 5000 Series takes it further with enhanced weight reduction and superior heat management through its aerospace-grade aluminum hat construction.

The two-piece design pairs a high carbon cast iron rotor ring with a lightweight 6061-T6 aerospace-grade aluminum center hat, fastened together with National Aerospace Standards (NAS) bolts and crimp nuts. This floating assembly allows the cast iron ring to expand and contract uniformly as temperatures rise and fall during braking, minimizing warping and distortion for long-term performance and reliability.

T3 Tri-Symmetrical Slot Design:

• DBA's patented T3 bi-directional slot pattern features precise CNC-machined tri-symmetrical slots for a quieter, more responsive braking feel
• Slots continuously evacuate brake pad friction dust and gases, preventing glazing and improving pad bite under extreme braking conditions
• Symmetrical design allows universal left/right fitment

Key Features:

• XG-150 High Carbon Alloyed Iron rotor ring for optimal thermal performance and pad interaction
• Thermal Stability Profiling (TSP) — proprietary heat treatment process that relieves internal stresses from manufacturing, maximizing thermal stability and reducing metal fatigue
• Thermographic Heat Paint (TGHP) — color-changing paint stripes indicate when the rotor reaches critical temperature thresholds, helping monitor braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and reduces the potential for pad knock and premature wear
• "Kangaroo Paw" vane ventilation pattern — 144 diamond and teardrop-shaped pillars promote faster cooling while maintaining dimensional strength
• Black anodized aluminum hat resists rust and corrosion while reducing unsprung weight for improved vehicle handling
• Center-split core castings for increased heat dissipation and thermal efficiency
• Recommended for high-performance street, track day, club racing, and rally applications

The DBA 5000 Series T3 represents the pinnacle of two-piece direct replacement brake rotor technology, delivering the thermal management and braking consistency demanded by performance drivers both on the street and on the track.
