I have an opportunity to purchase a set of rims from a 2016-19 CTS-V.

After scouring all posts I can’t seem to find if the offsets will fit.

The specs are as follows:
Fronts- 19x9.5 with an offset of +23
Rears- 19x10 with an offset of +39

Any insight would be great and help In terms of if I should purchase the rims.

Thanks in advance.

Search wheel or wheel offset calculators. You can enter your stock wheel dimensions and the wheel you are considering. 1010 tires site has one.

Think of a 2nd gen V and a G8 as basically interchangeable. I'm aware of only 1 guy who ran a 3rd gen V wheel on a V2. There was a fair amount of work needed to allow them to work. For that reason I don't think they would work without a great deal of work on a G8. Unless you can test fit, I would pass.

Both widths and offsets will be putting the outer edge of the tire outside your wheel wells.

The offsets are pretty aggressive for the stock g8 fenders. Will minimally need a roll, maybe even need to trim fender liner, pull fenders and add camber.

No amount of pulling is going to fit a 9.5" wheel on the front with a +23et offset. He'll be banging fender liners like no tomorrow.
