DBA DBA52120BLKS 5000 Series T3 Two-Piece Slotted Brake Rotor with Black Aluminum Hat

The DBA DBA52120BLKS is a premium 5000 Series T3 two-piece performance brake rotor engineered for extreme road and track applications. This advanced rotor combines high-carbon cast iron friction rings with an aerospace-grade T6061-T6 aluminum center hat, secured with National Aerospace Standards (NAS) bolts and crimp nuts for maximum reliability under demanding conditions.

Key Features:

• Two-piece composite design significantly reduces unsprung weight for improved acceleration and handling while minimizing heat transfer from disc to hub
• Uni-directional T3 slotted design features precision CNC-machined tri-symmetrical slots that increase pad bite, reduce brake fade, and continuously de-glaze pads for consistent performance
• Thermal Stability Profiling (TSP) process subjects XG-150 high-carbon alloyed iron to controlled heat cycles, relieving internal stresses for maximum thermal stability and reduced metal fatigue
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop-patterned pillars provides up to 20% improved cooling efficiency compared to conventional straight-vane designs
• Thermo-Graphic Heat Paint (TGHP) markings change color at critical temperature thresholds, allowing drivers to monitor peak rotor temperatures and optimize pad selection
• Black anodized aluminum hat provides corrosion resistance and aggressive appearance while allowing uniform radial disc expansion

DBA recommends the 5000 Series for high-performance street vehicles, track day and club racing, rally applications, and show vehicles. On average, these rotors last three times longer than conventional performance rotors. The lightweight two-piece design delivers superior braking performance while reducing rotational mass for enhanced vehicle dynamics.
