17x7's 4" backspace??

I am looking to buy torq thrusts II, 17x7 with 4" back space for the front of my 67' dart. I am planning to run 215/50/17's. I have measured or tried to.. but not 100% sure if they will work? Anyone have any experiance with this??

If I want more backspace.. they are special orders and cost like 60 bucks more a wheel. So I am trying to see what I can do with the 4" backspace first.

Thanks Bryan
