DBA 5000 Series 2-piece drilled front rotor for 2018–2021 Subaru WRX STI applications. The 5000 Series is a composite two-piece direct-replacement design that pairs high-carbon cast-iron rings with aerospace-grade T6061-T6 aluminum hats, joined with NAS bolts and crimp nuts. The XD finish adds non-directional cross-drilled and dimpled geometry for improved cooling and a sport-oriented appearance.
