370Z Annoying Rear Clunk

Check your diff bushings. If you see a black streak running down the diff, the rear factory liquid filled bushing is done and needs to be replaced.

Checked and no signs of failure. The clunk is not related to on/off throttle it strictly occurs when hitting bumps in the road.

Did you check your pre-load on your coilovers? That's when you jack the car up under the spring bucket while the car is sitting on jackstands in the rear. You should jack up 1/2in. before the car starts to lift off the jackstand.
