AVO avoS2C07G1HS018J 18mm Rear Sway Bar 02-07 Subaru WRX/STI
AVO created a solid 18mm rear stabilizer bar to give you the confidence when cornering and when you need the handling.
The WRX 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 tires during heavy cornering. This stabilizer bar is adjustable for 2 settings and includes polyurethane bushings.
