Subaru WRX STI (2015–2021) Exterior FAQ's

Please read our FAQs page to find out more.

Which exterior mods add real function to the 2015–2021 STI?

Front splitters, brake‑ducted fog bezels, and well‑designed wings add stability and brake cooling. Skid plates help protect the underbody on rough roads.

How can I ensure paint match when adding exterior parts to my STI?

Unpainted parts allow proper prep to your code. If pre‑painted, verify color in natural light and check clear‑coat thickness before install.

Will aggressive aero scrape on a lowered STI?

Consider adjustable splitter rods and reasonable ride height. Many kits include spacers to fine‑tune clearance without sacrificing stance.
