Is for a pair of discs.

DBA’s 4000 Series T3 is the ultimate in direct replacement single-piece performance brake rotor. 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.

DBA’s revolutionary universal slot design eliminates the need for separate left and right slot designs seen in traditional rotor designs.

DBA’s 4000 Series T3 rotors are recommended for all performance applications from street driving, 4×4 and SUV, light utility vehicles, track days, rally cars and armoured vehicles.

T3 rotors are denoted by the suffix (S) in 4000 Series part numbers.
