I'm about to order a set of Advan RS-D wheels from Japan for an Evo 9. Since those would be coming from Japan I have no room for error regarding the size, they can't be easily exchanged with a different size. I have to carefully chose the size, after reading several posts about Advan wheels I decided to go for 18x8.5 with +31 offset (lowest available for 8.5). It might be kind of a conservative choice, but I'd really hate to have to roll the fenders or have the tires rub against wheel housing. I think that 8.5 with the right tire size would still look as good as 9's!
Any ideas, suggestions?
