if you REALLY want to squeeze a 9.5" wide rim upfront you need ET 34-35ish then space it 10mm for the rear. its been done, but tbh.. you be better doing it with a 9 inch rim for the square setup, but it does have some awesome advantages if you can work it, but your going to need lots of - camber, great for the track/weekend cars, not so much for DD.
