Fronts should be 1.75" backspace. For a 15x10 to correctly fit a 4th gen F body you need 7.5" backspace, which they don't offer in the Jegs/Summit brand wheels.

Yep 7.5 is whats needed. If you go to 5.5 BS you have to narrow the rear end.

how far out would the tires be with a 15x10 with a 6.5 bs? does anyone have any pics? Do I need a large spacer, or can't fit a larger tire in the future?

You can run a 15x4 with 2.25 back spacing
