The DBA 5000 Series drilled front rotor for 2015+ Audi RS-3 is a two-piece direct-replacement rotor that pairs a high-carbon cast-iron ring with an aerospace-grade aluminum hat (T6061-T6), fastened with NAS-standard bolts. This composite design reduces unsprung weight, improves heat management and allows controlled radial expansion. The XD drilled and dimpled finish enhances cooling and structural support, making it suitable for high-performance street and track-day applications.
