Vibration 80-85 mph
Anyone notice a vibration at 80mph or so while the transmission is in 8th gear. It feels like it’s in the front end but no shimmy in the steering wheel. It sort of comes and goes. Can’t figure out if it’s coming from the transmission or engine. I do notice a lot more vibration in the wheel as compared to my 2022 c8. Maybe it’s just the fpc engine gives off a lot more vibrations then the pushrod v8. Not sure if anything is wrong or that just the way it is. Feels like my 2022 was more stable at higher speeds. Is your z06 smooth at higher speeds. Maybe it’s the stiffer suspension or wider tires.

That is not typical of C8s or C8Zs. You need to check for wheel balance, alignment and/or bent rims.
No problem with my C8Z at 150 MPH for 90 miles.

Nope. Mine is perfect. Definitely check your alignment. Possibly bent wheel from a pothole.

Negative. Sounds like a tire issue. Balance them would be my first move. Before they even take a weight off have them run the wheels and make sure not bent.

Put it in neutral at about 85 and still hear and feel the vibration. Has to be tire, wheel, or maybe rotor. They should fix it under warranty. Only have 500 miles. Should not have to pay for rebalance of wheels. Alignment feels fine. Not pulling at all.
