DBA DBA52994GLDS 5000 Series T3 Slotted 2-Piece Brake Rotor with Gold Aluminum Hat

The DBA DBA52994GLDS is a 5000 Series fully assembled 2-piece brake rotor featuring DBA's acclaimed T3 slot design and a lightweight black-anodized aluminum hat. Engineered for high-performance street driving, track days, club racing, and rally applications, this rotor delivers a significant upgrade over OEM braking components.

5000 Series 2-Piece Construction:

• Two-piece composite design combines a high-carbon cast-iron friction ring with an aerospace-grade T6061-T6 aluminum hat
• Assembled with National Aerospace Standards (NAS) bolts and crimp nuts for secure, precision fitment
• Aluminum hat reduces unsprung rotational weight for improved acceleration, deceleration, and handling response
• Allows uniform radial disc expansion through the cast-iron ring while minimizing heat transfer from disc to hub

T3 Slot Technology:

• Tri-symmetrical CNC-machined slots increase exit points for brake pad friction dust and gases
• Delivers a quieter, more responsive, and smoother brake pedal feel
• Bi-directional slot pattern allows use on either side of the vehicle

High-Carbon Iron Ring Technology:

• Cast from XG-150 high-carbon alloyed iron to minimize warping and cracking under sustained heat
• Thermal Stability Profiling (TSP): a proprietary DBA heat-treatment process that relieves internal manufacturing stresses, maximizing thermal stability and reducing metal fatigue
• Kangaroo Paw ventilation system features 144 diamond and teardrop-patterned pillars, delivering up to a 30% increase in surface area and 20% improvement in cooling efficiency over conventional straight-vane designs
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation, reducing the potential for pad knock and premature wear

Additional Features:

• Thermo-Graphic Heat Paint (TGHP): color-changing paint markings indicate when the rotor reaches critical temperature thresholds, helping drivers monitor braking temperatures and optimize pad selection
• Paint protection on non-friction areas reduces corrosion and prevents rust formation
• Gold-finished aluminum hat for premium aesthetics

The DBA 5000 Series is DBA's top-tier rotor line, recommended for high-performance street vehicles, dedicated track builds, and competitive motorsport use. This rotor is sold individually.
