DBA DBA52830BLKS 5000 Series T3 Slotted 2-Piece Brake Rotor - Black Hat

The DBA 5000 Series T3 Slotted Brake Rotor (DBA52830BLKS) is a fully assembled, composite 2-piece direct replacement performance brake rotor featuring DBA's patented T3 bi-directional slot design. Built on the foundation of the proven 4000 Series, the 5000 Series adds significant upgrades in weight reduction, heat management, and overall braking performance for demanding street and track applications.

T3 Tri-Symmetrical Slot Design:

The T3 slot pattern features precise CNC-machined tri-symmetrical curved slots that increase the number of exit points for brake pad friction dust and gases. This results in a quieter, more responsive, and smoother braking experience with greater consistency and effectiveness at every stop. The universal bi-directional design eliminates the need for separate left and right rotors.

Key Features:

• 2-Piece Composite Construction: High carbon cast iron rotor ring paired with an aerospace-grade T6061-T6 aluminium alloy centre hat
• Aluma-Lite Centre Hat: Lightweight aluminium bell reduces unsprung weight, allows uniform radial disc expansion, and acts as a heat barrier to minimize thermal transfer to wheel hubs and bearings
• NAS Hardware: Hat and rotor ring are secured with National Aerospace Standards (NAS) specification bolts and crimp nuts
• Kangaroo Paw Vane Technology: 144 diamond and teardrop pillar ventilation system delivers increased surface area for greater heat dissipation, minimizing brake fade and extending service life
• Thermal Stability Profiling (TSP): Heat treatment cycles realign the microstructure of the iron for increased rotor stability and durability under extreme thermal loads
• CBN Machine-Turned Finish: Cubic Boron Nitride precision machining minimises disc thickness variation and reduces the potential for pad knock and premature wear
• Thermographic Heat Paint Markings: Temperature-sensitive paint changes colour at specific thresholds, providing a visual indicator of peak braking temperatures and rotor fatigue
• Anodised Aluminium Hat: Anodised finish prevents rust and enhances appearance
• Modular Design: Complete assembly for first-time replacement; replacement rings are available separately, allowing reuse of the aluminium hat
