They have forged wheels on the ZL1 camaro but not on the corvette.

Maybe there can be ANOTHER class action suit this time for inferior wheels. How many other design flaws will be revealed before someone gets the ax at GM for engineering inferior products?
Forged wheels should be standard on a Corvette. Can't understand why the Camaro has stronger wheels.

All the wheel options are non forged aluminum, unlike the camaro ZL1.

Your dealer may have a road hazard warranty available but make sure it cover wheels and to what extent they are covered.

You can't have everything for 65k people. The car beats the GT3RS and the 570S on a road courses and does it looking damn good. They have to compromise somewhere.

You want DCT's, forged wheels, carbon everything and low weight...spend 220k and you can have it.

Very pleased with my machined faced aluminum wheels. Have had no issues in ~9 months.


Have had no issues with my C6 Z51 wheels, top pic,
2014 C7 Z51 "Rotary Forged" wheels middle (where I hit a deep hole very hard and bottomed the right front suspension and was sure I damaged a wheel-and didn’t,) or
2017 Grand Sport machined faced aluminum wheels (also Rotory Forged by Ronal!)

what about the guys that spent $100k plus on a Z06? Can we have wheels that donít bend and crack or is that asking too much?

Huh? So wheels that literally get ruined by driving on public roads should be acceptable on cars with MSRPs of 60K and up? When my last car, a $40K 370Z with sports package had Rays forged alloy wheels? How much more would forged wheels have cost? I have to believe there was some room in a 60K -110K budget to squeeze in wheels that w9nt destroy themselves by driving.

I get why they aren't standard on the base car and maybe even Z51. At the very least, they should be an option. The GS and Z06, it should be standard.

the MSRP on my 370Z Sport/Touring was $38k and the Rays forged wheels never let me down.

These wheels always got compliments

There was a good video from the Bash introducing the C7 showing how Ronal makes wheels (the video stated in Mexico for the Z51.) Lots of cold work resulting in a very strong, light weight wheel. (Note cast aluminum is malleable and can be worked and deformed like forging. Get the impression from this Thread some equate cast aluminum with cast iron that is chemically different [to get it to flow like water,] brittle material-it is NOT! Try beating on cast iron and you'll have broken pieces!)

Find it funny everyone keeps on calling the Vette wheels cast when at the start of this Tread this is what Tadge said, quoting;

“I will try to address. I would like to start with your comment about “Chinese wheels”. No Grand Sport wheels come from China. In fact, the majority of our wide Corvette wheels (those most susceptible to bending) are produced by a company named Ronal which is based in Switzerland and manufactures wheels here in North America.”

Found this info “some, who don’t have their mind already made up” might find useful! It describes what was called and shown in the Bash Video as “Rotary Forging:”

Spun-Rim, Flow-Forming or Rim-Rolling Technology
This specialized process begins with a low pressure type of casting and uses a special machine that spins the initial casting, heats the outer portion of the casting and then uses steel rollers pressed against the rim area to pull the rim to its final width and shape. The combination of the heat, pressure and spinning create a rim area with the strength similar to a forged wheel without the high cost of the forging. Some of the special wheels produced for the O.E.M. high performance or limited production vehicles utilize this type of technology resulting in a light and strong wheel at a reasonable cost. O.Z. has used this technology for several years in their production of racing wheels for Formula One and Indy cars. O.Z.'s Formula HLT wheel for the aftermarket is an example of a wheel produced using spun-rim technology.

High Light Technology (HLT)
The High Light Technology (HLT) process used in the manufacturing of select O.Z. Racing wheels uses rollers to compress and elongate the material along the barrel of a low-pressure cast aluminum wheel to obtain the desired profile. This process, which is directly derived from O.Z.'s experience in F1, produces wheels that are extremely light and strong. (My Comment: This is exactly what was shown in the Bash video as being used for the Z51 wheels vs cast mentioned used for the base car!)
The flow-forming process and the HLT technologies combine to create mechanical characteristics similar to those of a forged wheel. This permits a dramatic reduction in wheel weight while enhancing structural rigidity vs. a standard cast wheel. (This is O.Z's term for Rotary Forging!)

All the above said it’s the wheel design IMO NOT the manufacturing method that is the issue!

Default All four wheels bent, 6000 miles

I took my 2017 GS in because I felt a vibration in the steering wheel , told them to check balance on all four wheels , turns out all four wheels are out of round 😡 they was able to balance them but two are worse than the other . I donít believe this is from the ruff roads because the right front and left rear are the worse ones. Gonna go to my dealer and see what they tell me. Needless to say Iím steaming mad right now.

Our problem is the small size of the Vette population. So anyone who has had this happen, I hope you go to the Feds and complain so the problem can (hopefully) be recognized as recall-worthy. Sqeaky wheel time.

What's next with this car?

When you spend $100k on a car you would expect the wheels to last more than a few thousand miles without bending...

These wheels should have been forged from the factory Like the ZL1 camaro which costs around the price of a BASE stingray.

Instead the dealers get away with price gouging customers for $700 a wheel for a replacement.

My Nissan 370Z had forged wheels and cost me $36,000 when purchased new. Never bent one on the street or the track and I drove it through Chicagoís potholed streets 12 months a year. The Z06 wheels would bend in a week there. I donít know how anyone drives a corvette and doesnít bend these wheels on northern roads.
two cracked wheels in two years,,,no apparent damage,,,I know that I have not hit any pot holes etc, and I know four people who had the same exact problem, the crack starts in the barrel and runs 1 1/2 inches out to the bead and the entire bead has a hair line crack and leaks air

again I had two C6s and never had a problem,

Butch

Maybe if enough of us BITCH to GM they will listen

I borrowed z06 wheels from a friend and put cup2 tires on them. I did 2 or 3 track days on them- nothing more. Drove maybe 200 street miles. Somehow bent one.

Track has no hard curbing or anything.

As soon as I can decide which color I want, I'm getting a set of signature wheels and selling my OEM wheels.

Any recommendations of forged wheels you think look good on a Grand Sport?
