18"/19" stagger pic's

[Wall]

With 20" the sidewall starts looking small and the weight of the wheels and tires starts to become an issue. Unsprung weight not only effects handling, but also ride quality.

I definitely wouldn't want a smaller sidewall, I'd run a tire with roughly a 4in tall sidewall on a 20 and that should fill out the opening. And I'm mainly talking about the fore and aft gaps that need to be filled up. I think the car below looks good, it's a 19/20 setup.
