The DBA 5000 Series replacement ring for 2015–2020 Ford Mustang (GT Performance Package) rear applications restores two-piece rotor behavior using a high-carbon cast-iron ring that mates to aerospace-grade T6061‑T6 aluminum hats. The NAS-fastened composite design reduces unsprung weight and improves heat management, and replacement rings let you reuse 5000 Series hats for performance street, track day and rally applications.
