What drivetrain parts fit my Subaru WRX STI 2015-2021 (VA chassis)?
Every drivetrain part in this collection is fitment-tagged for the VA-chassis WRX STI (2015-2021), its 6-speed manual and its DCCD Symmetrical AWD system. The DCCD hardware changes mid-run — combined control on earlier cars, exclusively electronic control from 2018 — so confirm your year on the product page before ordering.
Did the DCCD change during the VA STI run?
Yes. For 2018 the DCCD changed from combined mechanical and electronic control to exclusively electronic control. It is the same system name with different hardware behaviour, so match DCCD-related drivetrain parts to your car's side of the 2018 change.
