Both sets will fit fine, the 225s will be a little stretched on the 18x8s. Assuming 225s on the 17s, they would have a good sidewall profile and offer some curb protection, if that is a concern for you. The 17s will also perform better, because the rotational mass of the wheel barrel will be closer to the hub.
Stock B5.5 ET is 37, so 8mm isn't going to make a huge difference in flush, especially since the barrels are 1/2" or 1" wider (17s and 18s, respectively). But I think both would benefit greatly from spacer applications, probably 12mm on fronts and 8mm on the rears.
IMO the 17s will also feel better. 18s can be pretty harsh if you elect to install or already have a sport spring/damper suspension. If you don't, I certainly would recommend that upgrade, it will transform your car. Another consideration is that if you are going for a look, the 18s have a lot of open area between spokes, so you better have a BBK or your rotors will look like bagels behind them. ;-)
The reason for running thicker spacers at the front is that the suspension components are closer to the wheel and that must be compensated.
Here is wheels I went with... sorry not really sure i get the spacers size. If i understand the suggestion was 12 up front and 8 in back. I though most run bigger in back and smaller up front. Thanks for helping me out.

Rather than answer you in PM Eddy, here's your answer:With 235x45x18 tires 45et what would be the spacer size to clear suspension?
I cannot answer that without: 1. your wheel width; 2. your wheel offset in mm (ET); and 3. your tire width I'm mm. Then I can show you how to use calculator.eddymarsh said:The only calculator I saw told me stock size vs new size. I just want y o know how far I have to have safe backpacking. The only spacers I could get were 30 mm. I have about a half inch clearance between tire and suspension. Would 15mm be safe bet or 20
