I'm seeing a lot of people getting large wheels; sizes such as 17x9.5, 17x8.0 and so on. Even getting a wheel like the Enkei RPF1, the weight and price of wheels in this size can get up there.
So, i'm assuming people are going for those size wheels to increase grip and to control oversteer. Now, my topic question is, instead of getting these large wheels, making them wider and wider, adding weight. . .could you not do a suspension/aero set up to make those large wheels less necessary?
For instance, could you not just add a GT Wing and adjust the rear toe to Toe Inward 0.5 degrees, leave the rear sway bar alone or remove it, while stiffening up the front a bit? I would think that setup would control your oversteer enough to be able to benefit from smaller lighter (and cheaper) wheels.
Am i wrong in this?

My history has been with small FWDs and trying to fit the smallest possible wheel over the caliper (typically 15'') and only going for a 205/50/15 tire, as to keep the overall weight of the wheel/tire at around 33lbs. Not to mention the effect smaller wheels have on acceleration and top speed.

You have to balance output with grip to find the ideal setup for your application. For most people, this involves wider rims and tires. Remember, this car likely has substantially more output than your FWD. The fast FWD guys I know all run large rubber (usually the largest that will fit or allowed by the rules) to match their output (B18, built K20/K24, etc.)
One could argue that oversteer with this car is a setup or driving error, and using an alignment and aero to bandaid that doesn't eliminate the source of the oversteer.
