The DBA 5000 Series replacement ring for Ford Focus RS (2016–2018) front applications is part of a composite two-piece direct-replacement rotor combining a high-carbon cast-iron ring with an aerospace-grade aluminum hat. The HD finish offers an OE-style smooth rotor surface while T6061-T6 hats and NAS hardware reduce unsprung mass and help manage heat.
