The DBA 5000 Series replacement ring for Volkswagen GTI (2015–2021) Perf Package 340mm front rotors is a component of a composite two-piece direct-replacement rotor using a high-carbon cast-iron ring and an aerospace-grade aluminum hat. The aluminum hat and NAS fasteners reduce unsprung weight and lessen heat transfer to the hub.
