DBA 12+ VW Golf R MK7 / Audi S3 Front T-Slot T3 4000 Series Rotor - 42830S

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: Painted non-friction areas to prevent rust and enhance appearance, or full En-shield coating to protect the rotor and alleviate the need for pre-installation cleaning.
• 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.
• Thermographic Heat Paint: Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
• CBN: CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation and the potential for pad "knock" and resulting premature wear.
• High Carbon Alloyed Iron: Formulation allows for optimal interaction with DBA?s thermal stability profiling (TSP). Increases the capacity of the rotor to handle constant and extreme heat over prolonged periods.
• Kangaroo Paw: Unique Kangaroo Paw vane design for up to 20% better heat dissipation, increasing braking effectiveness and prolonging brake life.
