I don't have any answers for you, but just wanted to send a hearty thumbs up. In an Impreza world gone mad, where the second question (after "How can I get 350 horsepower from my WRX?") is "How low can I drop my car?"
And you want to raise it! Hats off, my man. I raised my WRX wagon a bit for the snowy season, too. It sounds like you're seeking something permanent, though.
