The DBA 5000 Series drilled rotor for 2015–2021 Nissan GT‑R Nismo front applications pairs cross-drilled and dimpled cast-iron rings with aerospace-grade aluminum hats for enhanced cooling and structural support. The XD finish provides better cooling than HD and adds sport aesthetics; the NAS-bolted two-piece construction reduces unsprung weight. DBA offers rings separately so you can retain or refresh 5000 Series hats.
