As it turns out the stock rear sway bar on the base model Impreza’s is a wimpy 13mm paperclip. Found a 17mm off of an 06 Impreza. It came with the end links, bushings and even the stronger mounts. After some heavy doses of penetrating oil, the old bar came out and new one went in. What a difference! Anyone who has a 13mm RSB on their impreza needs, I repeat needs this upgrade.
On top of the obvious lowered rear roll, the turn in now feels sharp and much less of a under steering pig. At the limit a quick off throttle or weight transfer will see the back start to kick out in the most controlled fun way you could imagine :D
