Correct offset / Backspacing for 1970 Charger

[vita]

I have a 1970 Charger RT that I'm looking to get some 15" rims (to clear 4 piston Wilwood brakes). Is this the clearance I'm needing for the backspacing and offset to have these line up and look good? Not trying to get these to stick outside of the fender...

Also, If I was to go with an 8" rim up front, what would you recommend for the backspacing? I'd go with the same 7" rim style.

I run a 17x8 in the front with a 4.5 backspace and 17x9 with a 5 inch backspace.

The vehicle is pictured, so I figured a 10 in rim on the rear might not be a bad idea. I dont think a 9" rim will be able to hold any amount of tire over 50% throttle.


Thoughts?
