I had to replace the lug nuts on my C7 because the flimsy, hollow little things were more decorative than practical. I replaced them with solid lug nuts that didn’t warp and twist every time I pulled off a wheel. Does anyone know if that is a problem on the C8? If so, have you replaced them and with what from where?

Are you a NASCAR crew chief? Just stabbing at the lug nuts with the trigger pulled on your impact air wrench?
Not sure what the recommended torque is on the C7, but the C8 is 140 ft lbs. They are some pretty tough nuts
I am careful I think. I don’t use an impact air wrench, just a bar. But I do remove the wheels at least twice a year with the seasons and sometimes more often if I need access. I did manage to warp a few of the stock ones on my C7. Solid lug nuts solved the problem. My brother is the service manager of a Ford dealer in Texas and he tells me that a lot of people complain about warped lug nuts on Fords. Not exactly the same, but the same capped design with thin sheet metal as the cap.

This is actually valid and accurate. I've had mine off a few times and can see where they aren't as crisp of shape as before removed and no impact was used. The only problem I have with any of the solid nuts (McGard, Gorilla, etc.), is I do prefer the stock shape and look and none of them offer that shape, hence I have haven't done anything yet.
The problem with these factory lug nuts is denting, disfiguring, distorting the acorn type cap that is fitted over the original lug nut. This can happen in several different ways and for different reasons:
- Using an impact wrench on them. The hammering from the impact distorts the cap making it hard to fit a socket over them on the next service.
- Improper torque too tight distorts the cap making it hard to fit a socket over them on the next service.
- Not using the correct size socket (I believe correct size 19 mm on the C7) distorts the cap making it hard to fit a socket over them on the next service.
- Not fitting the socket all the way onto the lug nut causes a dent or crease in the lug nut cap distorting the cap making it hard to fit a socket over them on the next service.
- Rust forming on the nut under the cap causes the cap to bulge out therefore creating a problem when trying to fit the correct socket on the nut.
C-7 nuts started to show sign of rust. No warping. Take wheels off in the fall after 3-4,000 road trip to get tar ***** offf of inner wheel. Replaced with solid steel powder-coated nuts with lock nuts. Still looking good @ 42,000 miles. Ordered C-8 12/12/20.
I sold my 2014 Z51 w/56k miles on it, the wheels were off numerous times for various reasons, and all the stock lugs & locks still looked fine. I always torqued to spec by hand but would occasionally hit them with an impact to quickly get them off or spin them on (before final torquing by hand). Are people possibly using the wrong size socket? I'll have to double-check, but I'm almost positive I used a deep 21mm (or maybe it was a 19m?) 1/2-in drive.
IMHO the OEM lug nuts that GM puts on the Corvette are crap. I replaced the ones on my C7 with McGard lug nuts. I wish I would have removed them before I traded but I forgot. I just threw the OEM ones in the recycle container.

I've swapped between summer and A/S tires every spring and fall since fall of 2015, and my C7's lug nuts look fine. What are you using for a socket? Mine is a deep socket with plastic at the bottom. If you're not using a deep socket, you probably should be.
The stock C8 lug nuts are 2 piece and as usual the outer "cover" is starting to bulge and distort. No, I don't torque them to 10000 ft pounds they are just a poor design. I will replace them very soon as if you have ever had one of this style of nut fail, you know what a pain in the *** it quickly becomes.
These have the same shape and are one piece. I haven't purchased them yet, but probably will, the stockers are cheap. (don't mind it says Camaro, they are 14mm x 1.5mm)
You're probably going to want to use something like this anyway so buy it and give it a try. If you don't like the way your lug nuts look after a while then look for other lug nuts. As mentioned, don't use an impact wrench and torque them appropriately.

Phil....let us know how they work out, maybe an installed pic?....interested.
FWIW, neve had an issue with my two C7s BUT used a special lug socket that had a plastic insert. last I looked it was on a Porsche website for ~$40. Worked fine for the 100 ft-lbs BUT doubt the plastics would hold up to the C8 140 ft-lbs IF you could fine one. Recall I bought that when i had my 2008 C6. prior I was using a plastic bag uct to use just one thickness. Lasted about 1 wheel. Never use an impact wrench.
For the C8 22mm lugs bought this Titan socket. But like all that advertise no marring it's make of hardened steel. Only the outside is plastic as is the small inset inside (which I don't bother to use!) Just be careful with your wrenches and you should not hit the wheel on the socket sides anyway! It does have a rounded area on each corner that makes it only contact the flats. So far replacing brake pads, charging two rear tires because of flats- lug nuts look fine. Won't go back to using plastic bags unless necessary!
Are the 2022 C8 wheel lug nuts this size:
m14x1.5 7/8" hex
I would like to secure my 4 wheels by installing a secure lug nut like this model here: https://www.amazon.com/McGard-24019-...rolet+Corvette
If you have a better suggestion then please share here.
Thanks.

Yes, that's the right size. McGard makes quality parts
