Oil-canning-
A moderate deformation or buckling of sheet material, particularly common with flat sheet metal surfaces. Typically caused by uneven stresses at the fastening points. This terminology also refers to the popping sound made when pressure is applied to the deformed sheet forcing the deformation in the opposite direction.
Is what your hearing a metal "Popping sound" coming from the rear of the car? When your driving very slow over an un-even surface (Say a speed bump) the car will twist just enough to buckle the Aluminum sheet just behind the seats...thus Popping.
GM recommends the dealership take a hammer and pound the crap out of this, basically putting in dimples which will strengthen the Aluminum sheet. Something's wrong when a fix requires a hammer....
And yes, this problem is in the coupes, GS' and Z06's.

It is the sways no question. I had this exact same issue on a number of occasions over the years. Once it actually was the front sways and the noise traveled such that it sounded like the rear. So when you get the sways checked also have them check the front. I went through the axle nut and the rear diff fluid before finally getting the problem correctly diagnosed. I'd bet money this is your problem.
Most likely sway bar end links.
