The DBA 5000 Series replacement ring for 2005–2006 Pontiac GTO front applications restores two-piece rotor performance with a high-carbon cast-iron ring designed to work with DBA's aerospace-grade T6061‑T6 aluminum hats. The NAS-bolted composite construction reduces unsprung weight and improves thermal management versus one-piece rotors. Rings are sold separately so you can reuse 5000 Series hats for street and track use.
