I have not heard of anyone putting much in terms of Impreza parts on their Outbacks on this forum.
There is the occasional member that does want to lower their Outback but they generally turn to Legacy and Legacy GT parts as they share the same platform.
Not saying its not doable, but I wouldn't expect much info here. You might look around on the Legacy GT forums and see if anyone has done anything over there with Impreza coilovers. If you can do it to a Legacy GT then you can probably do it to an Outback.
Also, since the part is aftermarket, chances are the vendor will specify which applications it will work for.
