Emission, do you have a side shot of your car? I want to see how it's sitting?
Poodles, I agree, super ridiculous wheel fitment isn't good for car that gets driven. But I don't like the way Rajunz car looks. Maybe it's just the way it's sitting or that it looks like too much tire on the wheel or something.
I don't know though, I'm thinking something like a 9"+20 with a 245 and a 10"+25 or so with a 275 combined with a proper ride height and good alignment would look pretty awesome on a supra and be more tire than most people will use. That should fit pretty nicely and with rolled fenders not rub on anything. And if people want to wider, there's a lot of room to go in on a Supra.
But people should just play with that wheel offset calculator that I posted somewhere in here. The excel spreadsheet based one. I was just playing with it a little and if you base it off of known fitment, you can come up with different sizes and offsets and even estimates on tire profile that will fit within a given space. I was just using MKIV TT front wheels and the XT-7's that I was running. So 17x8+50 (right?) and 18x9.5+12 and messing around to see what was the biggest I could fit safely. It ended up being like 18x10+24 with a 255 and I'm pretty sure there is still room on the inside for more wheel. But I would have to test fit it first and find out. But at least it gives you an idea.
