DBA DBA52430BLKS Series Slotted Two-Piece Brake Rotor with Black Hat - 5000 T3

The DBA 5000 Series T3 Slotted Rotor combines premium materials with race-proven engineering to deliver exceptional braking performance for high-performance street vehicles, track days, and rally applications. This two-piece composite design features a high-carbon cast iron rotor ring paired with an aerospace-grade T6061-T6 aluminum center hat, secured together with National Aerospace Standards (NAS) bolts and crimp nuts.

Advanced Two-Piece Construction:

• Lightweight aluminum hat reduces unsprung weight for improved vehicle handling and acceleration
• Allows uniform radial disc expansion as temperatures rise, minimizing warping and distortion
• Reduces heat transfer from rotor to hub, protecting wheel bearings and suspension components
• Anodized black aluminum hat prevents corrosion and enhances appearance
• Replaceable rotor rings available for cost-effective future maintenance

T3 Slotted Performance Technology:

• Patented tri-symmetrical T3 slot design provides quieter, smoother, and more responsive braking
• Bi-directional slots effectively evacuate friction dust, gases, and water for consistent pad bite
• Continuously cleans and refreshes pad surface, preventing glazing under extreme conditions
• Symmetrical pattern allows universal left/right fitment

Premium Materials and Processes:

• XG-150 high-carbon alloyed cast iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment realigns the iron microstructure for maximum durability
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop pillars increases cooling efficiency up to 20%
• CBN (Cubic Boron Nitride) machined finish to micron-level precision minimizes disc thickness variation
• Thermo-Graphic Heat Paint markings change color at critical temperature thresholds to monitor rotor performance

DBA 5000 Series rotors are engineered for drivers who demand race-grade performance with extended service life. These rotors typically last three times longer than conventional designs while delivering consistent, fade-resistant braking power under the most demanding conditions. Ideal for weekend warriors who drive to the track, compete, and drive home.
