Shop Grimmspeed parts for the 2015-2021 Subaru WRX STI. The VA-chassis STI kept the EJ257 2.5-litre turbocharged flat-four and Driver Controlled Center Differential (DCCD) all-wheel drive - every Grimmspeed product in this collection is fitment-tagged for that exact vehicle, so check the product fitment notes against your car before ordering.
Everything in this collection - each product listed here is a Grimmspeed part fitment-tagged for the 2015-2021 Subaru WRX STI. Fitment can still vary with trim level and factory options, so confirm the fitment notes on the product page before ordering.
Not interchangeably - the VA STI kept the EJ257 while the WRX moved to the FA20, so STI engine parts are EJ parts, not FA20 WRX parts. Everything in this collection is tagged for the STI specifically; check fitment notes rather than assuming WRX crossover.
