need spacers for new set of wheels - 18x8 and 18x9.5 - advisable?

I bought a set of Boss Motorsports 338 wheels (they look identical to American Racing VN338 wheels) from someone local. He said he had them on a Chevelle (A-body). I made the assumption they would fit my car, but they do not.
Fronts are 18x8 with 0mm offset, so I am assuming 4" back space. 245/40/18 tires.
Rears are 18x9.5 with 0mm offset, so I am assuming 4.5" back space. 275/40/18 tires.

The front wheel's do not totally clear the center hub and there is about a 1/4" of space between the wheel face and the surface of the disc.

The rear wheel sits flush on the drum and over the hub, however the inside tire of the wheel is rubbing the rear of the frame I believe. I couldn't pass cardboard between the wheel and the frame, but couldn't get under to see for myself.

I am thinking I am going to run either 1/4" or 1/2" spacers with new studs front and rear and see if it helps. Is this advisable, or should I change the wheels out for a different design?

I have a 1/4" solid aluminum spacer drilled for the correct lug pattern of the car. I am not a fan of multi-lug pattern "universal" spacers. My 13"x7" reverse offset Daytons will hit the brake caliper without it. The 1/4" spacers for me have never been an issue and that is on a car with hydraulics so sees a lot of unusual forces lol.
As far as a 1/2" in the rear for ya. I can't speak too. I would be curious if when you get new studs if you would/should get ones that are longer as well? Will be watching this thread to learn for "down the road" experiences.
