I have noticed going into driveways at an angle and things that put a twisting load on the chassis it sounds like the rear glass is being flexed... No good. Anyone else have this happen and did a rear strut brace or similar help with it?

I would check nd tighten all your front and rear crossmember bolts and nuts along with suspension bolts and nuts wouldn’t hurt!

I just installed coilovers recently so those are all tight. But it was doing this on struts too.
Xmembers I'll have to check. Doing front poly bushings soon I have them just been busy. Need to order rears and go through all of that.
But beyond a flat out missing crossmember i don't see why any of that would cause so much body flex that it puts stress on the glass you can hear

My driveway is steep and angles across the property, making for a potentially frame-twisting transition from the street. I've never noticed that behavior with any of my SCs, even on firm suspension.

Pull down your headliner. You'll see bolts that hold the sunroof down to the roof, make sure those are tight. Before i removed my sunroof i had a clicking noise in the back when traversing over road transitions and found it to be bad clips holding interior panels and also loose bolts holding in the moon roof.

If you have a lot of suspension modifications, a strut bar will help a bit. however, the only way to make all the noises go away is a rollcage..

In your case, solid rear subframe bushings would help. so would aftermarket swaybars with spherical bearing endlinks, such as BattleVersions.
