I'm running 17x8 ET 45 with 12.5mm spacers, so an effective ET 32, and I'm just tucking under the fenders and about .5" from the inside of the wheel to the coil over tube with 2.5? of camber. A 17x9 will *just* clear the coil over with another .5" of poke and, to fix a 17x10 (if there was such a thing) I'd need another 12.5 of spacer, bringing me to an effective ET 20 and 1.5" of poke over the 17x8 - not gonna happen. It won't be quite as bad with a 15" wheel, but I doubt that the tire height of something that makes sense on a x10 wheel will be that much different over a 205/40x17. I think that the situation is worse in the rear.
