Ok..so this is a huge problem for me right now. I adjusted my rear preload to where it's supposed to be, and as you saw in the photo, the rear end of my car was sagging by quite a bit. With all the extra preload removed and a saggy butt, I went for a drive around the block, maybe 2 minutes, just to see if the ride quality had improved. I found that it had not. It's much harsher on the high velocity compression than before the car was lowered. It seems really crashy now. I'm going to remove the wheels and dampers and jack the suspension up and down through the full range of motion to make sure there's no binding, but i'm almost certain there isn't. It's just a ride quality difference.

Why would the ride height affect harshness with these type of shocks where ride height/damper length and preload are independent of each other and stroke length?
