I'm looking to give my 2006 impreza wagon a lift nothing major just an inch or 2. I have a full set of 04 wrx sedan springs and I want to get a set of forester struts and I know im going to need trailing arms but I have some questions about the swaybar stuff. Are the sway bar mounts welded on the the chassis or bolted, will I need new sway bars themselves and whats this anout the cartboy links? Cheers for any answers.
