8"
@ srankin90: 8 inch!? that's ambitious..!
running 6.5" all round on mine. there is very slight rubbing on the front inner arches so i'd presume if you were to fit 8", you'd proli only get away with it at the rear..? even with hubcentric spaces, you'd only move the rubbing from the inner arches to the outer wheel well.
someone else who may have attempted this may be able to advice but i wouldn't go down this road unless that car is only for straight-line driving..
lol
