Apex ARC8 17" vs. 18", Offset, and Tire Size Questions

[Vas]

Not with that attitude!

Anyways, that info helps. Thanks, Vas



I can get my 255/35/18 rears to break loose if I try, but when I drove my father's on significantly narrower 225/45R17s Pirelli P Zero All Seasons, the broke loose at fairly similar speeds, maybe a few mph slower, which was surprising that they had that much grip.

Sigh. I think I'll be happy no matter what I do given the significant weight savings in all options, just need to make an executive decision.

Sorry. I don't follow. 😕

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.

Yup, those are the decisions I'm weighing. On the ZHP you have with 235 sections, is that a square setup? Did you find any significant loss of grip from the switch?

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

Looks awesome. Pics before BC's at factory height by chance?

For some reason the photo is restricted, but your non coilover photo looks great. I really love the look of the concave wheels!

Thanks for the input, I'm considering the 18s on 235 section tires. Well I'm considering all of them but it helps to have people chime in who have experience with specific wheel/tire combinations.

If it was for the 17s...

It looks like they had a group buy for 17s that ended on 10/27. I wonder how often that'll come around.
