In this case, 8" is the widest you can go without rolling your fenders and doing some serious fitment work.
Sometimes I forget the fender differences between the wagon and sedan. My apologies. 8.5" wheels with 245s will rub on a wagon.Odd.. my 18x8.5 Rota Torques have no fitment issues on my bugeye. Although I am about to replace them with 17x8 RPF1s for reduced weight and save money on tires.. I would be getting 17x8.5, but even though I have STi hubs they are 04-05 hubs, which are still 5x100.. and they don't make 17x8.5 RPF1s in the 5x100 bolt pattern.
