Default What Offset, Size, and LUG Pattern do I need?

What Offset range can I use for C5 Coupe, LUG Patern? 5 X 114, and what is the max size I can use? I would like to run 345's in the rear. I know I'm going to have to tub the car out.

Bolt pattern is 5x120.65mm (or 5x4 3/4").

On a 12" rear wheel for a tubbed car, offset should be in the 74-78mm ballpark to fit flush and not stick out of the fenders.

Front wheel, if you're sticking to a typical 9.5" width..54mm is good.

Viper's use 6 lug wheels
No, they will not fit.

I was told that a Offset +64mm 18x12 rim doesn't need tubing?

If it's 54mm, then no, it may not. But it will stick out of the fender.

That is the only purpose of tubbing. To tuck a wider wheel/tire without it sticking out of the fender. Your initial post said you would tub, so hence my answer (for a correct fitment on a tubbed car)..

If you don't mind it sticking out of the fender, then you can run any width you want and not have to tub. Offset it accordingly
