The VA-chassis STI is one of the most modified platforms in the Subaru universe, and for good reason. The EJ257 responds to upgrades, the chassis rewards better suspension, and the aftermarket support is extensive. This collection brings together STI aftermarket parts for every corner of your 2015-2021 build from top brands Grimmspeed, Perrin Performance, Cobb Tuning, and more. 

  • Engine and drivetrain: intakes, turbo upgrades, exhaust systems, intercoolers, clutches and short shifters. 
  • Suspension and handling: coilovers, springs, sway bars, bushings and chassis bracing. Wheels and brakes to put it all to the ground. 
  • Let’s not forget the cosmetic upgrades: carbon fiber, lip kits, spoilers, lighting and interior accessories from JDMuscle.

Every product listing in our STI aftermarket parts collection has verified information, so you know what fits before you order.

FAQs

Do 2015 STI aftermarket parts fit all VA-generation models?

Many do: the 2015-2021 STI shares its core platform throughout. Engine, drivetrain, and suspension parts usually cross over without issue. Exterior components are the exception, since the 2018 facelift changed several body panels. Always check the fitment info on the listing.

What should I upgrade first on my STI?

Intake, cat-back exhaust, and a professional tune give you the most noticeable gains for the money and lay a foundation for everything after. If handling is your priority, coilovers or springs plus sway bars come first instead of STI aftermarket parts.

Will these parts affect my warranty?

STI aftermarket parts can affect coverage on related components, and most 2015-2021 STIs are outside factory warranty anyway. Check with your dealer if warranty status matters to your build.
