The DBA 5000 Series two‑piece slotted rotor combines high‑carbon cast‑iron rings with aerospace‑grade T6061‑T6 aluminum hats, assembled with NAS‑grade hardware. This composite design reduces unsprung weight, improves heat management and allows uniform radial expansion between the ring and hat. Recommended for high‑performance street use, track days and rally, the 5000 Series adds weight savings while keeping proven T3 slot technology for cooling.
