wheels
i have a 85 rx7 GS, its very hard to find wheels in the 4x110 size that are not for UTV/ATV. im lookiing for something other than stock in a 15 inch rim. anyone have any suggestions? or can i use wheel adapters to change the bolt pattern to 4x100?

I have been using wheel adapters to convert to 4x100 for at least 8 years. The only failure was 10 hours into a 14 hour race. Turns out I only installed 3 of the 4 nuts holding the adapter to the hub. Otherwise they have performed flawlessly. I really like the adaptitusa.com adapters, because they use lugnuts with a shoulder to increase contact of the lugnut to the adapter. I am sure there are other good ones out there.
The adapters I use are 25mm thick and wheel offset from about ET35 to et42 have worked fine. ET30 can work if the fenders are rolled. That is with 15x7 wheels and 225-50-15 street tires. Race tires tend to run a little wider so 225's tend to rub a little.
Just another option.

Take a look at VTO wheels.
vtowheels.com
They make a wheel called a Classic 8 in our bolt pattern in a 15” that clears nicely. Gotta like the spoked aesthetic though. Available silver and in black.

That looks really good

update. I just got off the phone with them. I’m thinking same rims. 16x7 with 20mm offset and 195/65 r-16 tires. Thoughts?

I would have gone 16 to fill the wheel wells a bit more aesthetically… but wanted to reuse some tires I already had.

they are telling me 20mm offset. I’ll be honest and say I don’t know what a 20mm versus a 32mm would look like on this car

In short your outside tire edge would be in the same place as far as poke goes. 1” wider tire, with its centerline 1/2” inward = same poke. (Approx due to tire shape, but close enough).
Gap between fender and tire would close 1/2 inch, if you had same springs as me.
Have you found comparison sites like wiltheyfit.com? It would help to enter the dimensions of mine, which we know the look of, then enter the dims of your proposed wheels/tires for a comparison. Pay attention to resulting diameter and poke.
If you got really clever you could photoshop one of my images and increase the wheel and tire size using the dimensions supplied by Willitfit.
My son also mocked up colors and wheel style in his Forza game!

Ha! Now you have given me something to do tomorrow. I am an old retired fart so always looking for reasons to get up in the morning. I will pull the wheels and check to see if I see any rub marks. Have never heard any rub, but will check for physical marks.

I am a retired old fart too and somehow manage to get up each morning and find something to do!
Is it possible that the ET32 listed on the VTO website is a typo? Usually, but not always, the offset will be stamped on the inside of the wheel. Or you can measure and do the calculation since you will already have the wheel off :-)

I'd rather bump the swaybar than fry a fender lip. 205/50/15s on a 7", +20 offset wheel will be pretty close to the fender.
I've had camber plates for so long I don't remember just how far you can go with all stock suspension, but I recall 15x7 +35 to be the sweet spot on a stock body (non -SE).

I entered in what I think the current wheels are and what I’ve been talking with them about getting.
so if I’m reading this correct, I’ll lose about 3.5 inches of fender space. So as long as I measure enough clearance for 3.5 plus travel ( no clue how much to add for that ), then they should fit.
I also see the MPH will be considerably off. I guess because of the larger tire.

Yes 90 is HUGE for profile.
I will pull my VTO wheels and check for rub this afternoon. Then, if no rub is seen, we can check what we know for sure fits versus what you propose.
And for sh*ts and giggles, here are the hand drawn calcs I did for the VTO wheels, before I realized there were online calculators!

Setec,
Have you taken off a wheel to check the size? The size and offset are usually marked inside. It has been a long time since I have had RA-1's on 7" wheels, but I don't remember that much bulge in the sidewalls. Those rims seem like they might be 6" or 6.5".
Having said that, it sounds like you are trying to fill your fender gap by using taller tires. As S-S notes above 195-90 seems way too tall (sidewalls). I did a quick internet search and tire rack doesn't have anything in that size and I couldn't really find anything else. I can't imagine using anything more than maybe -70- sidewall. I don't think you can fill your fender gap by tire/wheel size alone. Probably the most common performance-look RX7 tires are 205-60-13 or 205-50-15, which have pretty much the same diameter. A 205-50-15 has a diameter of about 23" and 205-70-15 is about 26", so you could reasonably fill about 1.5" of the tire/fender gap.
If the gap is what you want to reduce, you probably need to work with the springs.
Probably not very helpful info, but the best I got this morning.

and the 90 profile was pre coffee. I meant 60. (Getting old sucks)
I am going to need new springs as well. But also looking to avoid a 2k mistake. I figure new VTO rims and tires and springs easily set me back that much. In addition the the hit I took taking the car from my dad’s estate and transporting it here… and I still need to fix the rust, paint, and interior.
I can drop back to 15 inch rims and do the 205/50 15 combo. I think that uses the 32 or 35 mm offset if I’m not mistaken.
and yes. The goal is to give it a more sporty look and lose the massive fender gap and no, I haven’t pulled the wheels yet. It’s still in transit from Wyoming. .

OK, we have a verdict. 15x7 wheels with 20mm offset and 205/50 tires = no rub. I was wrong on the offset, they measure at 20mm not 32mm.
No rub on springs, sway bars, wheel wells or fenders. I would NOT go any larger in resulting tire diameter as this set up gets close to the front inside edge of the wheel well, see pic where you can see 'rotation' on the tire. Maybe you could push it a tad, and it would only rub on full lock.
Would not push the tire inside edge any further in so watch offset and tire width... current offset of 20mm with 205/50 tires just clears the spring but not by much. Also these are Racng Beat springs ,I believe they project the same amount as oem springs but dont shoot me if wrong.
So... when running tire and wheel sizes through WillItFit.com, I would not let your resulting diameter exceed 586 (well maybe you could push it a bit there), and would keep the resulting inset below 109mm.
No rub marks
Getting a bit close front wheel full lock, maybe 3/4" clear to inner edge of wheel well.
Spring clearance
Nice gap at sway bar
Tire size
Wheel specs stamped
This is what I get when I run my setup through willitfit.com

S-S - Not trying to be pedantic, but doesn't it say ET14 on the wheel? Maybe they are marked wrong, but if I am seeing that right it indicates 14mm offset not 20mm. The clearances in your pictures do look a little bigger than I have seen with Konig Rewind that I think are ET19 or 20.
Whatever offset they are, they are awesome looking wheels.
Setec - For what it is worth, the 205-60-13 diameter is about 22.7" and the 205-50-15 is about 23.1, so basically the same. Might start with lowering springs (~$300) first to close the fender/tire gap and save the expense of tires and wheels for later fine tuning.
