- Enhanced braking with T3 bi-directional slot design for smoother pedal feel.
- Anodised aluminium hat prevents rust and enhances appearance.
- Universal fit with symmetrical slotting for left/right use.
- Improved thermal stability and efficiency with heat treatment and unique Kangaroo Paw design.
- Thermographic heat paint for monitoring braking temperatures.
4000 Series T 3 is the ultimate in direct replacement single piece performance brake rotors Featuring all the benefits of the 4000 Series plus DBA's patented world renowned T 3 bi directional slot design.
Built on the foundations of DBA's T 2 slot, the T 3 slot design features additional, precise, CNC machined tri symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel The T 3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop.
We recommend a T3 slot for high performance applications.
T3 rotors are denoted by the suffix (S) in 4000 Series part numbers.
Product Features:
- Surface Design: Symmetrical slots and/or chamfered drill holes facilitate the exit of friction dust and gasses, for a quieter and more responsive pedal feel.
- Anti Rust: Anodised aluminium hat to prevent rust and enhance appearance.
- Bi-Directional Use: Symmetrical slotting and/or drilling for universal left/right use.
- Thermal Stability Profiling: Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability.
- Thermal Efficiency: Centre split core castings for increased heat transfer and thermal efficiency.
- CBN: CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.
- Thermographic Heat Paint: Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
- High Carbon Alloyed Iron: Formulation allows for optimal interaction with DBA's thermal stability profiling. Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.
- Kangaroo Paw: Unique Kangaroo Paw vein design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.
