Take your braking performance to the next level with DBA's 5000 Series replacement rotor rings. Designed specifically for high-performance street vehicles, track day, and club racing applications, these rotors offer optimal performance under the most strenuous circumstances.

Featuring a composite 2-piece design, these rotors combine high-carbon cast-iron rings with aerospace-grade aluminum hats (T6061-T6), held together with National Aerospace Standards (NAS) bolts and crimp nuts. This design allows for uniform radial disc expansion through the cast iron rings, reduced heat transfer from disc to hub via the aluminum hats, and further weight reduction.
