Recently, I made the switch from Style 135's to a square set of Arc8's, 18x9.5 +35mm. They are wrapped in 235/40r/18 Bridgestone Potenza RE70's. I ran these wheels for one week on factory suspension before changing to BC Racing coilovers.
Although most of the people in here appear to be leaning toward 17's with a taller sidewall, I'll still chime in.
I used the same tires on the 135's. After switching to the Arc's, I can say that I noticed a huge improvement in sure-footedness while cornering. The car did feel neutral, but more confident at higher speeds. I'm assuming that the change was due to moving from an 8-inch wheel to a 9.5-inch. There was zero rubbing with the factory height. As soon as I switched to the BC coilovers, I had to roll fenders to ensure that there wouldn't be any rubbing.
I run -2 deg rear camber and -1.5 up front. I daily drive my car, and don't race it at all, so I am not as knowledgable in the autocross/track department. I can say that I have noticed an increase in tramlining every once in awhile (especially now that it's colder), but nothing that I haven't been able to get used to. Overall I am very happy with my setup and think it's fairly practical for a dependable DD configuration.
And of course, picture time
