Forester strut assemblies, and Outback aren't very different. Forester springs may give you a little, but no where near an inch. There is some info about lifting Subarus in the offroad FAQ section. If you want to lift it, then you can add strut spacers, and bigger tires. If you want even bigger, you can use spacers for the entire driveline, but it's quite a bit more work. Also All the EJ trailing arms are the same, it's the brackets that are different, and Forester and Outback have the same brackets, so no change there. If you do spacers, you may want to add spacers to those as well.
