What suspension are you running? This would help some to know a little bit more about your car.
Here are some specs for the tire size compared to stock, So far if your running stock springs they will fit, I would even say that these should fit with swifts, you might not be able to run that wide on wrx springs or sti springs with out having some camber and maybe a 3 or 5mm spacer.
I would guess these will not fit without spacers. I had 18x8 48 offset ROTAs with 245/45/18s on them and it was extremely close to the strut body. Search around in the "will these wheels fit?" thread, you should find your answer there.
Thanks for the quick replies guys. I got all excited about them because they look so nice, then wifey decided she doesn't like them, so I guess the search continues.
On the other side of this conversation. A good friend ditched his 97 legacy outback wagon and still has his 15'' steelies with Blizzaks on them. They are mine if they can clear the brakes. I didn't see anything about them in the sticky thread about which tires are compatible (great thread BTW).
