DBA DBA52908BLKRS 5000 Series T3 Slotted 2-Piece Brake Rotor Black Hat

The DBA 5000 Series T3 is a premium two-piece composite brake rotor engineered for high-performance street driving, track days, club racing, and rally applications. Combining a high-carbon cast iron rotor ring with an aerospace-grade 6061-T6 aluminum center hat secured by National Aerospace Standards (NAS) bolts and crimp nuts, this direct replacement disc delivers exceptional durability and heat management under the most demanding conditions. The anodized black aluminum hat resists corrosion and adds a clean, aggressive appearance.

T3 Bi-Directional Slot Design:

Building on DBA's proven T2 slot pattern, the patented T3 design adds precisely CNC-machined tri-symmetrical slots across the rotor face. This increases the number of exit points for brake pad friction dust and gases, resulting in improved pad bite, a quieter pedal, and more consistent braking performance stop after stop. The symmetrical slot layout allows for universal left/right fitment.

Key Features:

• Two-Piece Composite Construction: High-carbon cast iron rotor ring paired with a lightweight 6061-T6 aircraft-grade aluminum hat, joined by NAS-spec bolts and crimp nuts
• Aluma-Lite Center Hat: Reduces unsprung weight for improved handling response and minimizes heat transfer from disc to hub
• Uniform Radial Expansion: The two-piece design allows the cast iron ring to expand and contract independently, greatly reducing the risk of warping and distortion
• Thermal Stability Profiling (TSP): Proprietary heat treatment cycles realign the iron microstructure to relieve internal stresses, maximizing thermal stability and fatigue resistance under heavy braking
• Kangaroo Paw Vane Design: 144 uniquely shaped pillars between rotor faces promote faster cooling and superior structural strength compared to conventional vane designs
• CBN Machine Finish: Cubic Boron Nitride turning minimizes disc thickness variation, reducing the potential for pad knock and premature wear
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint stripes change at preset temperature thresholds, allowing drivers to monitor rotor temperatures and optimize pad selection
• High-Carbon Alloyed Iron Formulation: Optimized for use with DBA's Thermal Stability Profiling process for maximum longevity
• Bi-Directional / Universal Fitment: Symmetrical slotting supports left or right installation

DBA (Disc Brakes Australia) backs the 5000 Series T3 with a 12-month or 12,000-mile warranty against defects in materials and workmanship. Sold as a single rotor; replacement rings are also available separately for cost-effective future servicing.
