Wheel "ticking" noise
Not sure when it started, but my front wheels are making a ticking noise when turning slowly (parking lot driving). Doesn't make the noise when driving straight. It sounds like a bouncing ping pong ball. I thought it was rocks in the tire treads, but upon closer examination, the noise is coming from the wheels or brakes. Can't seem to pinpoint exactly where, though.
I'm running A/S 3+ tires on OEM rims with carbon ceramic brakes. Any ideas what it might be or if I should be concerned?

I read that it's the rim where it meets the rotor. My driver's side front started doing it only on right turns and it drives me crazy. Tried removing the wheels and cleaning the area but it came back after about 100 miles.

I also had the same thing. I took the wheel off, cleaned the hub, and it's been fine ever since. Sounded like "tic-tic-tic"
Check your lug nut torque too - mine were all over the place from the factory.
Or could be the Ackerman effect mentioned in the manual.

Definitely not the Ackerman noise - that's basically gone with the A/S 3s.
It's annoying but I'm glad to know it's not just mine.

I had the same problem when turning right at low speed. Definitely not the Ackerman effect. Here is the TSB: http://www.corvetteactioncenter.com/...2016-1301.html
You can have your dealer do this if you trust them, otherwise it's easy enough to grab a can of brake cleaner and do it yourself. I picked up a can of the 19287401 AC Delco cleaner and did it myself. When cleaning the hub (on both the wheel side and rotor side) it didn't seem like I was making any difference honestly, but I put the wheel back on and re-torqued and the sound was gone. That was a couple months and probably 1500 miles ago. The sound has not returned yet, so it seems to be fixed.
Also, I only cleaned the wheel that was making the noise (rather than all 4 as the TSB suggests). The wheel hub did not seem overly dirty when I removed it, so don't get discouraged if it looks fairly clean to start. Similarly, I wasn't able to make it look totally clean, but it still worked.

I had the exact same thing. The Dealer was aware of the symptoms and it was a quick fix. It had to do with a break dust build up at the calipers. I did not witness the repair, but it was fixed within the day........

Some times the ticking is due to the two piece full floating brake rotors. The rotor rings move a small amount separately (laterally and radially) from the hats while the wheel is moving. The floating rings can compensate for some lateral run out in the wheel bearings and provide a better way to compensate for ring expansion and rotor coning due to heat from very hard braking as they are not rigidly attached to the hat. There are some videos on You Tube that show people using their hands to move the rings of aftermarket two piece floating rotors and you can hear them clicking.

As far as I know GM first encountered this issue with the 2009/2010 CTS-V's. IIRC I think they tried different rims with some hollowed out sections, then they tried different lugnuts (all with TSB's)...then they finally settled on the cleaning and torquing that is in the 'vette TSB. It solved it for some, but not for others.
My Z06 has the clicking.....it's on my list to do the cleaning and torquing on my own....but it is not really a priority. I'm over it.....

i had it on my car by the 2000 mile mark, and i had the dealer solve it at the 4000 mile mark. I have no idea what they did, but now that I am past 20k miles, i feel pretty lucky because it seems most people have the problem come back, and mine has not. I guess i should find out what they did to fix it and report back here.
