Tire Rack has steelies that clear 4 pots if that is what you are looking for. I can't tell you from experience if they work, but on the phone the guy I talked to seemed to know exactly what I was talking about when I mentioned the 4 pots.
Tire rack can get them for you, and I think they are $55 each http://www.tirerack.com/wheels/resu...preza+WRX+TR+Sedan&autoYear=2006&autoModClar= click that then click on steel wheels
