Did you mean "stock wheels?"

Because a square 255 fits under my stock body without rubbing.

I didn't say anything about stock wheels. I said what the stock body will acomidate. In the case of a s2k its a 255 up front and a 295 in the rear. Point being, if your running a non stag on this car, your leaving total grip on the table. But as mentioned, class rules ultimately will dictate the limitations and therefore what you find to work best within those confines. Generally speaking, unlimited class racing is more interesting to me personally.

Oh, gotcha! I thought you were saying stock 215 front was the most you could fit. I understand you now.

I understand completely.

I'm not looking to do anything, but thanks for the question. I was just noticing a LOT of people on the S2000 Talk forum talking about installing the same size wheel and tire front and rear. I just couldn't understand why. I auto crossed my car for three seasons with both stock S-O2 tires and Hoosiers with a front Saner bar. I always kept the offset. I never thought it needed more front tire.

I guess I also don't understand the distinction between "grip" and over/understeer. The first is a general characteristic, the second is a specific car's behavior at the limit of the general characteristic. How do you see them as two different things?
The first is NOT a general characteristic. We're talking about "how do I get more overall grip within the limit of my class rules."

If you don't ever get or utilize max grip, then you don't need more.

If you can get more grip (aero is an example) AND you can use it, it will be faster IF the suspension supports it.

Oversteer / understeer is often subjective and easily modifiable. Increasing grip is not.
Let's address one thing at a time and see if we can find a common point of reference. You have a street car with a stock suspension and no aero. You have decided to change the wheels and fit different size tires. You are never going to make any other changes, so future modifications are not a consideration. Would you go with a square set up and if so, why?

That kind of question is limited in scope and breadth to exclude itself from Racing and Competition sub forum.

If you can find a racing or competition class that does NOT allow you to modify alignment, then please PM me and let me know.

Your question is a very non-Racing / Competition question and will move this topic to Wheels and Tires for you.

What about classes where spring/swaybar changes aren't allowed? The stock class I run in with a local club allows wheel/tire mods, but springs can't be changed. Camber is limited to -2.0 degrees.

I autocross an AP1 with a square 255 setup and no suspension mods

Is there ever a reason to run square if you're not tracking your car? I ask only because I've potentially got a good deal on some Volk wheels, but they're 17x7.5 all around, running 215s. That's narrower than my AP1 in the rear, at least the tire is. I could probably get new tires in 205 and 225, but that'd be a bit off. The alternative is another set of AP1 wheels running stock size tires, I was just hoping to find something lighter.

Someone with experience driving in snow might be able to chime in, but I can't see a reason why you would need/want to run a square setup except for the performance benefits. That said, I don't think running a square 225/245/255 setup is going to hurt anything as long is you're not driving like a mad man on the street. I wouldn't run less tire than a stock AP1 has, though. Why make the car worse?

That's basically what I thought. Even if I did change the tires to stock sizes, it's not ideal since the fronts would be narrower than the rims. Running 225 all around without any other mods is going to affect the performance, though probably not too badly. However, given as I'm not a racing driver (nor all that good compared to some of the folks around here), I'd rather not do anything that's going to potentially increase my incidence of oversteer. The few times I've found that limit on public roads were enough for me.
