The DBA 5000 Series replacement ring for 2015–2020 Mini Cooper JCW Hatchback front applications brings two-piece rotor advantages using a high-carbon cast-iron ring matched to aerospace-grade T6061‑T6 aluminum hats. The NAS-bolted composite design lowers unsprung weight and improves heat management compared with one-piece rotors. Replacement rings are sold separately so existing 5000 Series hats can be reused for spirited driving.
