Loose Seat Back??
So I've seen plenty of posts about the "rocking seat" issue where the seat will move slightly on the seat rails, however I can't find any information on the problem that I am experiencing. The upright portion of my seat has a good bit of back and forth play to it, probably 3" to 4" at the top, and this is especially a nuisance under heavy breaking. Has anyone else experienced this? Could it be a problem with the seat back adjusters? Just curious to see if anyone else has experienced this and found a solution.

There's a few things that could be at play. There can be an issue with the seat-back adjusters. I didn't really look into it much because I found my issue to be something else.
The mounting tabs for the power seat rails can wear, which causes the rear of the seat bottom to move around. This makes it feel like the seat back is loose. To test, grab the headrest and move the seat back side to side. Watch what moves where the seatback meets the seatbottom. If the seatbottom is moving, it't the mounting tracks that are the issue.
For me, I just swapped my rails to manual rails and haven't looked back. Lighter, insanely rigid (seat doesn't move at all) compared to the power rails, slightly lower (more headroom) and simple to adjust. If you like the power seat rails, there's a kit that fixes it:

I'm going to assume this is a joke.
It's pretty clearly the seatback itself that is loose. I have no problems with the bottom of my seat moving as normally seen in the "rocking seat" that is often described.

It is part of the normal design. Its mentioned in the GM C5 Z06 video on youtube. I think it was a bad idea, but I do know it was purposely put there for some reason.

Still strikes me as an odd "feature".

"Normal" for corvette seats...terrible IMO. I had some special parts machined to eliminate 2/3's of the rocking. They still move a bit. I don't notice it under hard driving now though.
