DBA DBA53910BLKS 5000 Series T3 Slotted Front Brake Rotor 2-Piece with Black Aluminum Hat

The DBA 5000 Series T3 brake rotor represents the ultimate in direct replacement two-piece performance brake rotor design. This 356mm diameter front rotor features DBA's patented T3 bi-directional slot design, combining premium materials with race-proven engineering for superior braking performance in high-performance street, track day, and motorsports applications.

Advanced T3 Slotting Technology:

The T3 slot design features precise CNC machined tri-symmetrical slots that create additional exit points for brake pad friction dust and gases to escape, resulting in a quieter, more responsive, and smoother braking experience. This innovative slot pattern increases braking consistency and effectiveness while reducing pad contamination and heat buildup.

Premium Two-Piece Construction:

• High carbon cast iron friction rings paired with aerospace grade T6061-T6 aluminum hats, secured with National Aerospace Standards (NAS) bolts and crimp nuts
• Aluminum hats reduce unsprung weight while allowing uniform radial disc expansion and reducing heat transfer from disc to hub
• Kangaroo Paw ventilation design delivers up to 20% better heat dissipation compared to conventional straight vane designs
• Black anodized aluminum hat for corrosion resistance and enhanced appearance

Heat Management Features:

• Thermal Stability Profiling (TSP) heat treatment realigns the microstructure of the iron for increased rotor stability and durability
• Thermographic Heat Paint markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and premature wear

Application:

This fully assembled rotor is designed for front axle installation and is sold individually (two required per vehicle). DBA recommends 5000 Series for high performance street vehicles, track day and club racing, rally applications, and show vehicles.

What's Included:

• One fully assembled two-piece brake rotor with black aluminum hat and friction ring bolted together
• Ready for direct replacement installation
