AVO Turboworld Stabilizer Bars for the Subaru WRX/STI are designed to bolt into the stock factory brackets, and were set up for a good balance of street and track driving. This stabilizer bar includes polyurethane bushings to make the most of this suspension upgrade. It’s a huge improvement over the tiny OEM bars, removing body roll in corners and increasing driver confidence. Give your Subaru a sway bar upgrade from AVO. Picture is for reference only.
