I just put a set of 1" wheel spacers on my rear wheels. I have noticed that the studs stick out about 1/4 of an inch. See the photo. Is it common to have to trim these to make them flush?

 

If the wheel nuts that you're using to secure the adapters are recessed completely AND IF your wheels have a recess between the wheel stud bores that allow the wheel to be mounted "flush" to the adapter it would be fine.

If there's no recess between the wheel stud holes on the wheels then they will need trimmed or changed.

You don't have sufficient snapshots to completely answer your question.

Put up a snapshot of the wheel back-side that you intend to use. If your nuts aren't recessed you should be able to buy some that will allow complete recess IF the adapters are machined properly. There's many "IFs"!!

 

Looks like it's time for a cutoff wheel.

 

Maybe!

 

Just a educated guess. I am thinking that someone installed longer studs in the past. When I used 1" ADAPTERS (which is what you have) on my 85 to install ZO6 wheels, the studs were flush with the outside of the adapter. with 383vette, install the lug nuts to fasten the adapter to axle and use a cut off wheel and cut off the studs to be flush with the adapter.

 

Is it just the pic,
as it does not look like the black studs have threads?

 

They looked to me to be the "dog-point" also and generally the recess in the wheels that are "going on" will absorb the length of the "dog-point" IF the recess is present. The OP hasn't posted back so who knows what he's got. If it's only the "dog-point" then the cut-off wheel isn't an issue. It takes about 5 minutes for the OP to determine what it is that he needs to do to accomplish his wheel install.

 

Got it..

 

Theres no threads on the ends of the studs. I have not had a chance to post more pics, but it sounds like cutting them flush is the answer.

 

I’ll leave this here as it’s been mentioned before

9-4-2019 Dale Stevens 2 right side bent rims per dealer 2016 Stingray 15,400 miles

 

This is really irritating! I had my 19 GS at the dealer and asked them to check for wheel bending/cracking. They said that they were fine. But I only have 1100 miles on it. So, basically I am just playing the waiting game to HAVE a cracked/bent wheel on an $80,000 car!!!!! Now, I didn't pay that! But GM had the nerve to put that MSRP on the window sticker knowing full well that they made the car with inferior equipment!! Between this and waiting for the A8 shutter, GM has managed to take all of the excitement out of owning a Corvette!

 

Add my third crack first 2 rear now front 19 gs 12k miles additionally bent the other front but that one was on me

plmmd

 

In response to those who are wondering why I accepted GM's offer, my response would be that I had not yet spent any money out of pocket to replace the wheels. So, while my ask in arbitration was going to be for cash to replace the wheels with those from another wheel manufacturer, I chose not to walk away from a firm offer.
When a plaintiff receives a settlement offer just before going to trial, they have to decide if they are going to accept almost being made whole or going to trial where they may win big or may get nothing. I chose the former.
As to the GM wheels rather than cash, the arbitrator left as soon as we told him we had reached an agreement, so when GM changed to replacement wheels rather than cash he was already gone. We would have had to reschedule the hearing for yet another day. I chose to cut my loses in terms of lost time, as it were.
As someone else noted, if GM had just accepted the warranty claim when the cracks were discovered I have would have received replacement GM wheels and walked away satisfied. It is disappointing that so much time had to put into getting what they should have offered in the first place.
I will be quite happy to have new wheels and not have to worry about driving the car on the freeway or filling the tire once a day to replace the leaking air.
But I will indeed wonder when the next problem will arise and anticipate asking my tire shop to check the wheels every 3-4 months.

 

I feel the same way. After paying $85k for a 2018 GS, I have a car I’m reluctant to drive lest I run over a mouse carcass and bend/crack a poorly designed wheel. By the way, I had 2 bent front wheels at 1800 miles that cost $700 to repair.

I’ve had many corvettes starting with a used 1963 I bought in 1969. I’ve NEVER had an issue like I have with these substandard wheels that I had the privilege of paying extra for. Then to add insult to injury, GM legal hides behind the fact that they only warrant material and manufacturing deficits and won’t take ownership for design failures. Then good old Tadge has sold us out by not taking ownership of the problem and trying to tell us it’s “normal” to bend wheels on normal roads.

Chevrolet has destroyed my enthusiasm for corvette along with the other vehicles they sell that are under engineered and severely overpriced (e.g, Escalade). I hope Tadge and Mary are proud of their approach to cutting corners in the name of “performance”. If Chevrolet has cut corners on the flagship C7, one has to wonder what they are doing to their other vehicles.

Does anyone know if the C8 wheels are bending/cracking?

 

Doubt the C8 are bending or cracking as I don't believe they are as deep (wide).
