The DBA 4000 Series drilled rotor for the 2022 Subaru WRX front application is a direct-replacement drilled rotor designed to work with the WRX front braking system. It pairs the 4000 Series metallurgy with a drilled face to help evacuate pad gases and debris, improving pad contact consistency under heavy use while preserving OE fitment and installation characteristics for a simple brake upgrade.
