Clunk Clunk noise
I recently put a C6 Z06 rear sway bar on my '99. I have metal end links. Now I'm hearing clunk clunk, especially when one rear wheel goes over a rise and is higher than the other. I can hear it a low speed like in parking lots. We lifted the car. Everything is real tight. Any ideas?

If the noise is new with the new sway and links, I would guess you may have gotten a bad link. These are a common source of clunk type noise. The exhaust system is a common source as well.

Look at the space between the sway and the cradle. Stock had 1/4", installing the C6Z51 it was noticed by another member that he had less than a credit card space. I checked mine and it was touching.
Don't know if they caused the clunks, because I am lowered and am working through other issues as well, but I made some spacers to get the 1/4" space back.
Possible that when one side goes up, the A arm goes up and so does the sway, and it's hitting the rear aluminum craddle.
You'll see some pictures of Stock and then the spacers. I don't know if this is your problem, but I know I didn't like them touching as they are not designed too.

I have the same problem. I did a search and it might be the rear diff. fluid or the torque of your sway bar end links:
