Do we even need to Wide body?

If we go with 15 inch wheels, we would be limited to a 225/50R15 tire. These would fit in the original wheel well perfectly. Example.

These also show off the Black banana style wheels better.

The only problem with this is I'm not sure if a 225/50 is a wide enough tire for our power goals.

Ideally, I would like to run a 245 width tire, but I haven't found a 15 inch tire that wide.

Honestly though, I'm not sure if it's the lighting but that might be the best looking S30 I've ever seen. The color is perfect, the wheels are perfect, the ride height is excellent. Twin exhaust stack and duckbill wing? Yes. If my Z turns out half as nice as this, I'll consider it a win.
