The Impreza 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 21mm rear stabilizer bar to replace the small stock stabilizer bar to fix this area.
