If 8 and 9 are not considered 'over-tire-ing' then what is? I was always under the assumption that anything past 8 was just for looks... even on track. Granted I don't know much about this stuff.
btw, thank you Alan, you're helping a lot.

No problem. As you indicate, you're new at this. I remember when I first got into modding in 2000 and knowing absolutely nothing. 13 years and 7 cars later, I'm still learning, but enjoy helping others, especially those new that sometimes don't get answers. I should also add that this info is particularly fresh for me as I just bought new wheels and tires for my BRZ this week.
I think 9 is probably enough for most people with these cars. 10s seem to be pushing it except if you really need the grip at track/auto-x. But even then its a lot of wheel/tire for a 200hp car. You can always have more grip with a wider tire (and thus wider wheel). But the question is, can you exploit it and what are the downsides? Oversimplifying, a wider wheel and tire combo will add weight, may affect the feel and of course there is only so much space under the fender.
In most cases, whenever you "+1" (the term for adding an inch in diameter to a wheel), you will get a tire with a smaller sidewall heigh so the total diameter of the wheel/tire package is the same. Thus the wheel rotates the same number of times in a given distance. You would get an even smaller sidewall if you "+2" and so on. At some point, you just can't get a smaller sidewall tire and you run into a larger overall wheel/tire package which would then affect the rolling diameter and which would then affect the speedo/odo.
This link and the links on the page at Tire Rack will give you plenty of reading for wheel/tire education.
