DBA 03-10 RX-8 Sport Suspension Front Slotted 4000 Series Rotor

Experience the ultimate in braking performance with DBA's 4000 Series T3 rotors. 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.

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