As stated above, the rim's back-spacing is the key issue.  Next is the height (diameter) of the tire, as well as the width of the tire.

Those Year One 17x9 rims have the correct back-spacing to fit 275-40-17 tires on both Front and Rear of our E-bodies.  Those tires are actually pretty small in diameter...  and not really that wide... as some people think of the overall size.

Will a 3.5" backspacing on the front stick out closer to the fender lip than a 4.5"?

A 5" backspacing on the rear will sit further in towards the drum, correct?

Who has a 295/50r15 in the back?

What size rim should I do? 8" wide or 10"?

Will I need to relocate the springs or not?

WACO -- you do NOT want a 3.5" backspace on any rim.... unless you want that deep dish look... AND fender interference problems with any size tire.... regardless front or rear.

Neither, 9.5 is best. However, either of those will work. 8" requires you run lower pressure, 10" makes the tire look a bit stretched, IMO.

You will need to move springs for a 10" rim IF you want the tire to sit inside the fender lip. if your raising you car higher, then it may not matter. If your using a 3.5" backspace rim of either size, you absolutely will have to raise the car.

I've progressed over the years... using the car primarily for pylon autocross and hi-speed road course autocross (HSAX/HPDE).

Latest setup is Team III ET rims (vintage mini-lites), size 18x11 front and rear, backspacing 5.5".   Fender lips have long been flushed and slightly pulled; suspension is lowered and stiffly setup.   Current tires are Yokohama AO52 series 295-30-18, 200 tread wear.

Factory front spindles (Cordoba 11.75 rotors); factory 8.75" e-body differential.

Would I be able to run 15 x 10 deep dish auto drags with off set spring hangers and shorten my e body diff.
Or even find a b body diff

Depends on what you mean by "deep dish". The typical deep dish dimension for a 15x10 is 3.5" backspace, which means no, you can't run these without lifting the body or  narrowing the rear AND moving in the springs. The stock rear housing is about 2" too wide per side for those wheels to fit within the stock wells without significant modifications....or a lift kit.
