DBA 05-17 Subaru WRX STI Front 5000 Series Replacement Ring

The DBA 5000 Series T3 is a 2-piece direct replacement performance brake rotor ring, designed for high-performance street vehicles, track day, club racing, and rally applications. It features high carbon cast-iron rings combined with aerospace-grade aluminum hats (T6061-T6), secured with National Aerospace Standards (NAS) bolts and crimp nuts. This construction offers weight reduction and improved heat management. The T3 bi-directional slot design, with precise CNC machined tri-symmetrical slots, enhances braking consistency, responsiveness, and smoothness by increasing the exit points for brake pad friction dust and gases.
