4000 Series T3 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 T3 bi directional slot design.

Built on the foundations of DBA's T2 slot, the T3 slot design features additional, precise, CNC machined tri symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel The T3 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.

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
• Thermal Stability Profiling: Heat treatment cycles realign the microstructure of the iron, resulting in increased rotor stability and durability
• Thermal Efficiency: Center split core castings for increased heat transfer and thermal efficiency
