I have 17x9s all around, see pics in the "Sickest Foxes" thread.
but im running 255/40s up front, with 275/40s in the back, no quad shocks.
However, i also have SN95 front and rear conversion, so the wheel stance is a little wider than a stock fox body.
Only problems i run into now, is the rear fenders NEED to be rolled.
