2015-2021 Subaru STI Interior Parts & Accessories

Upgrades You’ll Notice Every Single Drive

Interior mods get overlooked because they don’t show up on a dyno sheet. But they’re the ones you interact with constantly. 

A weighted shift knob changes how every gear change feels. More deliberate, less notchy, and paired with a short shifter, it transforms the whole drivetrain experience. Aftermarket pedals give you better grip for heel-toe work and clean up a worn factory set. A proper steering wheel wrap or replacement fixes the single thing your hands touch for every single mile you drive.

Then there’s the practical side. Custom-fit floor liners protect your carpet from slush, gravel, and whatever else your build drags in. Storage inserts turn dead center-console space into somewhere useful. These aren’t glamorous, but they’re the STI interior mods owners never regret.

Start with what bothers you most. That’s usually the perfect first upgrade. 

Building a Cabin That Matches the Build

If you've already sorted the engine, suspension, and exterior, a stock-looking interior starts to feel like an unfinished sentence.

Carbon fiber trim overlays for the dash, console, and door panels are the fastest way to tie the cabin into a carbon exterior build. Alcantara wraps bring a more subdued, motorsport-inspired feel. Ambient LED lighting adds a modern layer after dark, with color-matched options that pull the whole scheme together.

For 2015 STI interior builds specifically, worth noting: the 2018 refresh brought changes to the infotainment surround and some console trim, so double-check fitment on dash and center console pieces. Everything else, shift knobs, pedals, lighting, floor liners, carries across the full 2015-2021 range.
