The DBA 5000 Series replacement ring for Audi R8 (2008–2019) front iron rotors is a component of a composite two-piece direct-replacement rotor featuring a high-carbon cast-iron ring and an aerospace-grade aluminum hat. The aluminum T6061-T6 hat, joined with NAS bolts and crimp nuts, lowers unsprung weight and permits controlled radial disc expansion, improving heat management for demanding street and track driving conditions.
