Default Anybody have trouble running 18's on a GC8 RS?

Thinkin about buying some 18in Gold Sub Zeros this summer and I was wondering if anybody advises against going that big on a GC8. I'll probably end up doing a 17 in the end but, i just wanted to explore my options first.

Ya, 18's will cause rubbing on a GM6/GC6.

Here's a nice pic of 19's on an RS though ...

im looking at 18s as well but i dont see why they would rub. if you can get 18x7.5 in 48offset, why would it rub? as long as you do the plus sizing on tire size, you should be fine. 35 or 40 profile tire should work fine.

, if you notice in the pic I posted the silver WRX next to it. That's the person that the 19's belong to. We just put them on the RS for fun.

Yes, you can do it without rubbing. However the question is, do you feel safe running 215/35/18s? I know the Subzeros are pretty strong for their weight, but I wouldn't run anything below the 45 aspect ratio that I'm currently running, though. Not everyone lives in Michigan, land of the potholes, though.

if you are not lowered, it should not be a big problem. If you are it will be.

I am running 18"x7.5 with a 48 offset on H&R springs. rubs when there is a load in the rear(ie people, stuff in the trunk).

I wouldn't recommend running 18s on the GC8. I tried it once just for giggles with 18 (but with 225, which rubbed on corners and bumps).
Aside from that, 18s are pretty heavy, so the car would tramline under braking. And instead of better stopping distances, it will actually be worse (more mass). Also, for 165 hp, it's really not worth it....

oh yeah...i finally took them off and got P1 17s on 215/45s. Best compromise ever between cost/weight/strength/handling. Hope it helps!

A GC lowered 1"-1.5" running 18 x 7.5 on 215/35 rubber should have no problem. It will rub just a tad bit in the rear when loaded with anything more than 180lb in the trunk or backseats. Don't even try using 225/40 rubber.

I only know because I did this with the 5Zigens currently on my turbo wagon.

not that it matters but ibis had 17 inch wheels with falken azenas (spelling?) and he rubbed because the falkens are the widest 225/45s that i've seen. wider then the 225/45 pzeros i ran which also rubbed in the back a little until i rolled the fenders.

i also don't see why an 18" would be a problem with the proper offset and a tire that isn't wider than 215 or a narrower 225.

don't ask me why one 225 tire is wider than another 225 tire... i don't know but companys seem to measure them differently.

When shopping for a tire, compare "Section Width" specs. That will tell you the actual width of the tire instead of the nominal width spec (ie. 225)

<------ waiting for the Azenis Sport to come out in a 215/45-17 or 205/45-17 size... could be a cold day in you know where before that happens!

I have an L with 18" Team Dynamics Motorsports and 215/35-18 Nitto 450. I'm at stock height and no rubbing. I have s-techs that I plan to install soon.

I bought the rims used from a guy who had them on his RS with 5-zigen springs and he said he only rubbed when there was full load in the rear.

Wise choice skipping the 18"s Brian. Yes you SHOULD know better, especially working on Strafford Ave. That place has potholes that'll SWALLOW your car.

I'm a 16" wheel advocate for the GC, though. I mean, 17" is beautiful, don't get me wrong, and if you do proper plus-sizing they should fit fine in 17" or 18" ... but I dunno, I like a nice set of 16"s on a GC.

This one, for instance, which I'm seriously interested in. It's the Prodrive GC06, which Prodrive-USA told me is available from Prodrive-Japan in 16." It's the cast version, not the forged one... I don't think forged comes in 16" or at least it sounded that way :



Looks a lot like a Volk TE37. I think Rays makes the GC07 wheel, maybe the GC06 too, so it very well could *be* a TE37 in disguise!

I still want to upgrade to the WRX/Legacy brakes , which means I'll need 16"s year-round at least, so... it's either keep my OEM wheels for summertime and find some cheap WRX rims for winter, or..... do OEMs for winter and new ones for summer, come next year. Dunno.

I was just in Durham last night, I should've Emailed you to let you know.

Oh, just FYI, I know that wheel is a four-bolt pattern. The only pic they have is of that one, they do sell them in 5-bolt for Imprezas. Figured someone'd catch that.

Just for arguments sake, you could use 18's effectively without rubbing. The p1 had a prodrive suspension option which had 18's. Supposedly it handled alot better than the p1 with 17's. Personally though i say 17'' OZ's baby.
