The COBB adjustable rear sway bar for 2008–2021 Subaru WRX/STI is a direct-fit 24mm option intended to tighten rear roll resistance and improve chassis balance. Its adjustability allows match-up with front bar settings to refine handling behavior. As a bolt-on upgrade, the 24mm rear bar helps reduce body lean, improve cornering traction and deliver a more controlled rear-end response for daily driving or track use.
