In reading all this about lifting an Impreza. I have a 2011 OBS, I'm looking at getting 2011 Forester struts and springs prob get 16" Forester wheels with the General Grabber tires. What's confusing me is what I need for the rear wheel relocation. I've seen mention of 97-99 outback trailing arm mounts, will these mount up to my '11? Would a better option be to do subframe spacers? Are the trailing arm mounts attached to the subframe? They kinda appear to be. Other than puttin on camber bolts and some sorta swaybar endlinks, are ther any other parts I need to consider? Thanks.
