AVOTurboworld designed 22mm Rear solid stabilizer bar is a big improvement over the original stabilizer bar fitted to the standard Subaru. It improves turn-in and removes body roll in corners. The Subaru comes with what can be described as an "adequate" suspension straight from the factory, but it does leave much to be desired. Too much body roll can lower confidence in driving, and does not allow you to use all 4 tyres well during heavy cornering. AVO created a solid 22mm rear stabilizer bar to replace the small stock stabilizer bar to aid in improving this area.
