The DBA 5000 Series cross-drilled front rotor for 2014–2018 Audi RS7 (with iron rotors) is a two-piece direct-replacement assembly pairing high-carbon cast iron rings with T6061-T6 aluminum hats fastened to NAS standards. The design reduces unsprung weight, allows controlled radial expansion, and improves heat isolation between disc and hub, delivering better thermal management for spirited street and track-oriented applications.
