The DBA 5000 Series two-piece drilled rotor for 2015–2021 Nissan GT-R Nismo front-left applications is a composite direct-replacement assembly combining high-carbon cast-iron rings with aerospace-grade aluminum hats fastened with NAS hardware. This construction reduces unsprung weight, improves heat management, and allows uniform disc expansion. Recommended by DBA for high-performance street, track day, club racing, and rally use, it delivers weight and thermal advantages over one-piece rotors.
