Front wheel hop at low parking lot speeds when turning
I am new to this site, I just purcased my first corvette and I love it. I have a 2014 c7, supercharged, z51, 3lt with F4 suspension and magride. I have been reading up on this annoying problem of the wheel hop/bumping noise when turning at low speeds in parking lots. i have taken it into my local chevy dealer and has spoke to a friend thats a master tech there. They have checked the ELSD fluid to make sure its full, I heard some c7's were shipped with low fluid and might be causing that issue. I do have the Michelin pilot super sport ZP tires on it that came with it. Are there any known repairs for this problem? Would changing to an all season Michelin tire fix this issue? Any info would be appreciated!

If your problem is what I think it is, it's been around for a long time and is not limited to Corvettes. It used to be called 'radial roll and can happen on any car with radial tires. The wider and lower profile the tires, the more pronounced the 'shake'. It only happens on the front and normally when backing up in a tight turn, not an ELSD issue. It's similar to backing up a 4x4 in 4 wheel mode and turning tightly.
How can you fix it? Basically, you can't. You can try taking much wider turns when backing up to minimize it but that isn't always possible. Short of putting skinny, tall tires on, there's not much that can be done. I replaced tires (for a different reason) on a previous Vette with All Season but it did not help. I'm surprised your dealer did not tell you this. |

Thank you for that info. That kinda sucks that I have to live with that noise. I bought this vette used from a high line non chevy dealer. So they were not aware of this issue.
The supercharger is an A&A |

Yes, it's the Ackermann effect. It was News to me too. 48 years of driving and owned untold number of vehicles over those years and my C7 is the first one to have this issue. Just something we have to put up with I guess.
