I've been trying to buy wheels, and not many people or vendors seem to know what offsets will fit on the car. I've looked in to other wheel posts,and there isn't much help there either.
Can any vendors, or customers who have put new wheels on their car, post what size, specs. and offset they got and maybe some pictures if possible.
I think it would help a lot of people who are trying to buy new wheels.

Been thinking bout aftermarket. What brands you been looking at?
Yes I know what the stock ones are. That doesn't help with aftermarket wheels.
It gives you a STARTING point.
19x8.5 +
52 20x11 +64
So, if you want a 19×9.5 you have added an inch to the width (9.5 is 1.0 more than 8.5 for the math impaired). 1.0 inches equals 25.4 millimeters.
Then you look at the fender clearance and decide:
a) If you want the 1.0 inches proportioned at the same track (0.5 to the outside and 0.5 to the inside) you add 00 to the 52 mm of offset and get 52
b) if you want the same outside width, you add 1.0 to the inside by subtracting 25.4 from the 52 and get 26.6 and you can round this either direction.
c) so depending on the measured fender clearance and your acceptance of, or aversion to, fender rubbing, you can choose any offset that suits your fancy.
Same math works at the rears.

I understand all of that, but I don't have the tools or garage to take the wheels off and measure that. That also doesn't predict if there will be any rubbing when turning.
I'm simply asking for people that have already installed, and what they went with.

If you're talking to a aftermarket wheel vendor that doesn't know the offsets. That today can't produce wheels to an widely available spec. You are talking with the wrong wheel vendor. Just walk away Renee.
We have proper offsets for basically any size you want to do from stock 19/20 to 20/21. Please also note that offsets do play a major role in fitment but just because Company A uses offset X does not mean the same offset if used on one of Company Bs wheel will work. Theres alot more that is determined by each manufacturer that is specific to their wheels and profiles as well as spoke geometry, and clearances. I have seen so many times guys buy a wheel and ask for a different wheel from a different manufacturer to be made with a specific offset they saw on someone elses vehicle and thats a recipe for disaster.
For example our Forgeline VX1 in 19/20 with our custom offsets fits the C8 but our VX1R in the same sizes and offsets does not fit due to spoke geometry.
Whomever you buy wheels from need to have measured an actual C8 and the manufacturer should have their recommended offsets based on the wheel your interested in.
We specialize in wheels such as Forgeline, HRE, Anrky and Brixton. We have measured the C8 and have our offsets depending on what wheel size and width you like.
Please if we can assist Call/Text 440-915-6166 and Ill be happy to help.
All our Forged Wheels are made 100% in the USA and have a long history of making wheels for our customers.
I dont check this thread often so please contact us if we can help, but we cannot give you fitments on other manufacturers we dont carry as they are often not identical as explained above
Please all Stay Safe and Congrats on your C8s.

OP, don't forget to factor in your ride height. If you plan on lowering at all, even slightly, the offsets you select will need to be calculated as such.
Ya I;m trying to figure out what those brands have done so I can use the specs for other brands, because I don't want to waste $5k on forged wheels.
That's why I'm asking for specs if anyone has actually installed them, and why I'm not asking for people to "guess" on measurements.
Good morning, I shared very valuable information on this thread which is helpful to everyone searching for wheels. One main reason some will not share is for the exact quote you mentioned, Some people like my self have been up and down the C8 corvette since last year, spending time, money and using almost every channel we have to locate proper specs and well each brand wants to keep the sale. I had this same mentality and well after getting to know many of the members and members on C8 Corvette groups I realized I was here to help first and sell second.
Here is the link, First post shows exactly what we did https://www.corvetteforum.com/forums...rr-wheels.html
also a little advice: Just because you order a wheel with the off sets listed dont mean the wheels your ordering will clear the calipers, thats something only the company you choose to buy fro will know or might not know. so keep that in mind and get a guaranteed fitment noted on your purchase order.
We had this discussion on the early 2014's. About everyone assured me that all C6 wheels would fit. This turned out to be false. Please pay very close attention to caliper clearance with the spokes. Her's a picture showing the interference.
Where do you plan to find 'real' forged wheels for $5K? That might get you the fronts? But then maybe not.
You're making my point even more... haha okay $10k. It's a waste of money in my own personal opinion. Cast wheels have always been fine for me and look fantastic.
