My intrax's w/my GR2's are way to stiff, and not low enough for me. What should I try next? I am looking into the Eibach sportline's because that is the ride height I would like. Any opinion's or comment's??

EDIT: I am also getting 17's in a month or two. My other wheels will be for sale(they have basically brand new Dunlop sp501's(225/45/16))
