I am gonna put on some 18X8s on and I was basically just wondering what offset to go with.

If this is for an FD, you should really run wider wheels. You would have to run 225/40s and give up a lot of load-bearing capability. Atleast run 18x9s so you can run 245/40s. 18x9s should be +40 to +45 offset.

 

what's the point of running 18x9's?

EDIT: I mean, isn't the stock width sufficient?

 

I dunno why everyone talks about running these widths. The previous owner put 18X7s on the back and i am running 245s on there right now. The tire is sucked into the rim so they don't really look like 245s but it works. With the 18X8s I can run the 245s and have them look like 245s, plus I can put 265s on when I get the extra money which won't be for awhile. I know, blahblahblah its too narrow for 265s, no its not just gonna have some tire bludge which doesn't bother me at all. **** my friend ran 275s or 285s on is Cobra with 8 inch rims without a problem.

 

With low profile tires, you don't have as much leeway to put a wide tire on a narrow rim. You can't run huge diameter tires on the RX-7 without rubbing fenders, so your tire sizes are limited.

You lose sidewall stiffness if you squeeze a wide tire on a narrow rim, too, which reduces the "crispness" of the steering response. I am all for wide tires, but I think it is better to get a rim that supports the tire when you do so.

If you just want 18" wheels for aesthetic reasons and aren't really interested in performance, narrow wheels are fine provided you can find some tires that fit on them. What you choose should meet your own personal requirements within the bounds of "what works". I got new wheels because I needed more tire, which also meant I needed wider wheels to get the performance I wanted.

yeah I (A) really like my rims and (B) really want some wider rubber on the back. But variable (C) is what kills me. I don't have the money to run an 18X10 rim sporting 275 rubber. I would like to. But for the immediate future I think 18X8 sporting 245s isn't a bad alternative. It depends how much for 18X8.5 or 18X9s are. When I get home on Friday I will have to go to Discount Tire and get some quotes. They are sweet and have hooked me up in the past.

 

I'd just suggest a 235/40/18 front and rear with anywhere between a +35 and +45 offset. That will work fine.

If you're looking for a wheel from Discount, contact us and we should be able to get you a better deal. At least save you on shipping or something.

For a well priced 18" wheel there's always the Enkei RPM2. They are light as hell and not that expensive either. They only come in this finish so check 'em out. What's your budget? I might have some quick suggestions. this does not include tires as those are a constant variable.
