anyway i was just wondering clearence issues with the front calipers. I dont mind shaving a few mils off em. Also will i need to use spacers, as i was running 225/50 RA-1s on the stock R rims and i used 5 mil spacers to make them clear the rear.

just to clairfy the wheels are 15x8 +25

 

wow! last year on stock suspension with some 15x7 +35's and 205/50's i was cutting my tires up pretty bad the first expo day, they were fine after i rolled the fenders on the second day.

 

With a +25 offset, I can't imagine spacers would be necessary, unless those spokes don't clear for some reason. You do realize they're heavy as hell right? The quote about the difference in wheel width vs. weight is a valid one (though I don't necessarily think superpilun's thought on "proper tire application" or whatever is). You can fit a 225 on a 15x7, and it might feel crappier than on a 15x8, but the rubber is still there. Check out Volks, SSR Comps, or special order Kosei K1s from Tirerack in the right size and offset (+38 or +35 I think). None of them are gonna be cheap (K1s are about $200/wheel, SSRs were around that last time I looked, Volks would be $$$), but if you want one that's at least reasonably light, those are the only options I know of. Cheaper, and possibly lighter than the one you showed (though heavier than the ones I listed) would be a custom Diamond Racing wheel or the like. I searched around for this a few months ago, and came up with depressingly few options. I eventually settled on 15x7 K1s.

 

i dont want to spend hella $$ on wheels. i rather spend the $$ on tires.
do you think these wheels will fit my ITR and if so what mods will i need.
thanx in advance

 

Do not get those.....get something lighter and that has the proper offset.

 

wooh.... those are huge..

 

they are 17lbs, whats wrong with the offset?

 

That guy is using them on his accord - which has the same size calipers as an itr... iirc.

The problem:

I'm in the market for some 15x8's as well... so far I've only found kosei to have 22 and 12 mm offsets in this size and 5lug.

I will be ordering two for test fitment from tirerack, presuming they are still available (I've heard otherwise).

 

Thank you for an Informative answer. I dont blame you for not wanting to grind on dem Spooner clappers. But i have always been cool with grinding the stock calipers. So besides the whole grinding thing what is your oppinion on fitment?
will i have to bend fenders? use spacers? w/ 25 offset?

 

my opinion is that fitment would be excellent.

you will of course need to roll the fenders a bit all around (depending on tyre size), but assuming 225/45/15's it won't be too bad.

no spacers will be needed.

volk used to make te37's in 15x8 in +27 and I would've purchased a set recently but they no longer make them. These are very close to that fitment.

I just have concerns about grinding on something that'll have to haul me down from 120+ mph repeatedly and endure the heat + stress abuses of the road course.

Even still, I'd get two for the rear of my car. They're that cheap.....

 

I wouldn't get 15x8 rims for an ITR.

What tires are you planning to use on them? Let's take an example and I'll show you why I say that. Let's say you're planning to use them for your 225/50-15 RA-1 tires. Those tires are approved for rim widths of 6.0-8.0 inches. However, I usually avoid the extremes of the approved rim width range, for looks as well as performance reasons - and at the top limit of the approved range, the tires are going to look stretched onto the 15x8 rim, and I seriously wonder the handling would be as responsive as it would on, say, a 15x7 rim, which is in the middle of that range.

Also, you won't be able to use tires narrower than 225, so if you didn't want to roll your fenders or you wanted to get 205/50-15 tires for street use, they can't be mounted on 15x8 rims.

Your decision, of course...

 

fwiw, i currently run 15x7.5 cp035's +40 offset for my street setup - 205/50/15 es100's. This is on my itr with no fender rolling, and it is lowered quite a bit.

I wouldn't hesitate to run 205's with a 15x8 and turn-in is actually more crisp as you approach the top limit of the approved range for the tire... 225's would be better for autox/ lapping days imho, but you can get away with a more narrow tire for clearance issues should you need to.

Wasn't Todd00 running 205 azenis on 15x8's?
I believe he was doing very well at nationals with that setup.....

The RT-215 Azenis worked freaking *fantastic* on a 15x8" rim. The RT615, not so much (7.5" is optimal).

As for rim vs tire, it's always better to be toward the max extreme if you are worried about overall performance. I know...I've tested back-to-back before with several different tires and wheel combos.

On a 225 R-comp, I wouldn't even consider running a 7" wheel. 7.5" minimum, but 8" being better.

 

I have run 225/45/15's on my STOCK ITR wheels. Turn in feels kind of sloppy but once you're in the turn it holds very well. They also god rid of my traction problems I had on the track under full throttle. My car is also very low and I only have slight rubbing on full lock. I'm also looking for a cheap set of 15x8's. I'll see if I can find some pics...

 

yes i have been running 225s on a 6" rim and they felt like ***. Every person i race with says that wider wheels work the best for responce, and even with a narrow tire.

todd00, why did the 615 azenis not work so well with the 8" rim as the 215?

 

and could i stregth say 205 r comps on my 8" rims? cuz thats what i would like to do after i kill my 225 ra1s

15x8 exceeds the approved range of rim widths for most 205 treadwidth tires, including the Yoko ES100 and the Toyo RA-1. Both have an approved range of 5.5-7.5 inches only.

Yes, but the RT-215 was notorious for the 205/50-15 tire being substantially larger than all other 205/50-15 tires. The RT-615, not so much.

FWIW, both 205/50-15 Azenis tires are approved by Falken only for a rim width range of 5.5-7.5 inches.

That's true up to a certain point, but not beyond it. (Otherwise, people would be using 15x9 and 15x10 rims, right? )

Come on man! Don't you know about the ultra cool vw guys and jdm drifters putting 185's on 7.5" rims. Its the cool thing to do.

 

i think a 205 on a 8" rim is a good idea as it gives the most ideal contact patch.
flat, not curved.

I'm looking very hard for a set right now. +0 to -25 offset please!

If you find any, please let me know!!!11
