I've owned my 2016 GT PP for about 2.5 years now, and I am proud to report that the notorious rear "bounce" of the S550 has been completely obliterated in my car. Here are the steps I took and the relevance of each fix:
1) Springs/Dampers: It is nothing new to hear that the dampers in the 15-17GTPP were not paired well with the springs. In stock trim it would feel at times like my car was a high-school-kid-owned low-rider complete with blown shocks and heated-to-lower springs. This feeling was especially noticeable when driving over the odd pavement that resides in tunnels and on bridges at higher speeds. I installed Ultralite Springs and ProAction dampers and my car became glued to the road; the only remaining bounce I felt was slight, and was only present at very low speeds.
2) Shock Mounts: I added these a few months after dampers and springs and the resonance frequency of the remaining "bounce" changed, almost to a point of complete obliteration. These bits helped provide more of the "one and done" sensation.
3) Tires: This is actually a new serendipitous development (for me) in my quest to destroy the dreaded "bounce". I changed to my winter tires a month or so ago (from the OEM Pzeros) and was amazed that the ever-so-slight-bit of bounce I had left (only felt at 35mph or lower and on rare occasion) was gone. I thought it odd that a tire change could have this influence, and then I read the following article while searching for new summer tires:

So there you have it: 3 concise steps to bring your Mustang into the land of the refined ride. I hope you all have a happy Thanksgiving and travel safe.

Low and behold, the remaining last bit of slow-speed bounce wasn't the suspension at all, but the tires. I seriously wouldn't have guessed. My compulsive psyche was pondering root causes from a general chassis design flaw to the no-spare-tire rear-axle weight differences in the PPGT. Alas, replacing the OEM tires was the final step to completely obliterate the "bounce" from reality.
