When turned fully to the right and crawling at slow speeds, I hear some clicking from what seems like the driver front wheel well. It's a rhythmic click happening at regular intervals as I go in circles. Turning to full left might be making a noise too, but I can't really tell. This started happening yesterday (~1400 miles on ODO).
Are there any specific areas to check under the car? Most of it is covered by plastic so I can't see much. Anyone else have this issue?
Thanks,
FS

Have the same thing, carbon wheels and brakes, I’ll let others chime in on the issue but I think it’s the wheel mounting surface itself? I have no rubbing on anything or issues on track besides clicking around some corners on track occasionally but less lately, as well as slow full lock.
The wheel(s) have to be removed, both the hub and wheel mating surfaces must be cleaned, apply a very light coating of anti seize spread on the wheel mounting surface, install wheel(s) and torque lug nuts in sequence (star configuration) to spec in 3 stages. GM has a maintenance directive on this with a lubricant they spec. Anti seize to be used very sparingly. Check lug nut torque after 1000 miles.
I don’t have the TSB handy but if you do a search in this forum for it there’s a discussion about a week ago where I posted it. The super lube mentioned in the TSB isn’t applied to the entire rotor hat surface. It’s only applied to the pilot bushing where it goes through the rotor. I’ve performed it a couple of times to my car. It’s a great time to clean the inside of the wheels or ceramic coat them while they’re off the car.
All the c8s seems to do this. My SR did this and my z06 also does this. My c8 sr actually did it for probably 10k miles or more and then one day it just went away and never came back. It did it a lot. My z06 barely does it but it does do it a tiny bit.
I use this socket. Its far from fool proof but it does help. I also loosen and tighten by hand, then torque to 140 lbs. I use these as well to help get the wheels off and on . Again, not perfect but helpful to not damage the calipers , wheels, rotors.
Ackerman effect is not eliminated by tire choice. I had it worse in my SR with PS4S than i did with my Z on Cup2R, so flawed logic if thats the only way you ruled it out.
These cars are not meant to be turned fully in either direction at any speed, and the quicker the speed at full or near full turn radius, the more the tires will "hop" across the pavement.
+1 on the non-marring sockets posted above. I use those too

Jacked up the car this past weekend and did not find anything damaged with suspension. Also, the noise mysteriously disappeared.
Maybe dumb question, but ff I were to removed the wheels, how do I not damage/mar/scratch the black chrome lugs?
