Upgrades Youβll Notice Every Single Drive
Interior mods get overlooked because they donβt show up on a dyno sheet. But theyβre the ones you interact with constantly.Β
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 thereβs 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 arenβt glamorous, but theyβre the STI interior mods owners never regret.
Start with what bothers you most. Thatβs usually the perfect first upgrade.Β
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.
