I picked up these rims on Facebook Market Place, I am a C4 guy and when I saw them I thought that maybe they were off a C6 but after looking at some adds on the Forum they maybe off a C8, so with that being said can someone that has knowledge with C8 tell me what I have here, really have no idea what I will do with them.
Yes, they are off a C8 Stingray, I have a set. And as many others will also tell you, they are worth nothing, many cannot even give them away. Hope you didn't pay too much for them. The market is flooded with these as people upgrade to other wheels and have no use for these basic stock ones.
Yes, C8, you may be able to run them on a C4, but te center bore is smaller, so you would likely have to open that up, at the very least.
Possible you may need wheels spacers too.
I believe I read that they will not work on a C4,5 6 or 7 the lugs are bigger and the studs are larger . I could be wrong on this it's been some time since I read that. The C8 was up graded also takes 140 ftlb of torque on lugs.

From Tadge Juechter:
Our move to a mid-engine architecture shifted mass rearward so that the Corvette's weight distribution is 40F/60R. We take advantage of that traction with more torque multiplication through our new DCT for improved acceleration. The wheel stud size, pattern, and stud count is based on the needed wheel attachment clamp load to account for vehicle axle load, tire grip and other loads that the wheel-to-bearing joint must endure. These calculations drove us to the M14 wheel stud size for the rear axle. Many generations of Corvettes have used 5 studs on a 4.75 inch diameter bolt circle. It was a very standard pattern for the industry. For this generation we are moving to the metric standard of 5 x 120 mm. This change has nothing to do with the loads, in fact they are very similar patterns. So much so, that some people may try to use wheels designed for one pattern on a bearing with the other. That is very ill-advised.I'm glad this question has been asked because we need to let people know about the potential mismatch problem.
Although not needed for loads, we elected to use the same design on the front axle to keep a common lug nut, similar bearing design, and aesthetics.

They will fit the bolt pattern, earlier cars have smaller stud diameter, but that is not an issue.
Smaller hub center bore and different offsets are the biggest hurdles.

5x4.75 BC is the same as 5x120.65mm, and is so close to 5x120 as to be negligible as to fitment, .65mm difference is just 256 ten-thousandths, and on a bolt circle you cut that in half, so 128 ten-thousandths difference.
Do as you wish, but it is really a non-issue, no matter what Tadge says.

Serious question. What are your professional credentials that we should take your advice over the Chief Engineer that oversaw the development and production of the C8 and C7?

Well that be be true but to me I found out that they're not bad wheels, not hard to keep clean and I didn't want to spend a ton of bucks on after market wheels and I don't care for black wheels so I did the wheel exchange with West Coast Corvette and got them chromed. Just saying !

Designer Imagines A Corvette That Looks More Like a Corvette Than the Corvette
Slideshow: A Jaguar designer's personal project imagines what a modern front-engined Corvette might look like if Chevrolet revisited the golden age of the Stingray.
