How much you looking to spend on wheels? cuz if you dont want to use spacers then your looking BIG money for something like a set of 19x10 et0 front and 19x11 et0 rear, even then you may still need a small spacer eg 20mm to bring them propper flush. Best bet imo would be to buy Attacks 20" wheels in the for sale section and then run some decent spacers to get the look you want, this way you can play about with different size spacers to acheive different offsets till you get what you want
