Well, they are off!
Not too bad to remove, They ended up being stroked out with just a tiny bit of compression still left after jacking the tire off the ground from a point on the frame. I was easily able to tap the bolts out in this position with little resistance.
I measured before and after heights (to the fender) - note there is a slight slope and my driveway is not perfect so you can't compare left to right, but you can the relative height change of each side. Left 55.4 -> 54.6, right 54.4 -> 53
I then drove to a fairly flat area to see the effect front-back. Before I had approximately 2.5" height difference in the habitat (rear being lower). Now that the front dropped by roughly an inch it is much closer.
Front right:50.7"
Front Left: 50.0"
Rear right:51.0"
Rear left:50.5"
Basically no height difference now so I'm super happy with that.
As far as suspension feel, I didn't have the dampers on so that will change things a little but the front suspension now feels much more plush. Was crossing over train tracks I have many trips across and before it would be harsh and rattle the cabin, now it's way smoother and you can feel the suspension soak up the bumps. Very very happy and seems like this is how A1Rs should be considering the only reason they have these springs is to support very heavy armor - that never happened. I may add a few hundred pounds in roof rack but that's probably it so I have no concerns there.
Now going to bust out a cutoff wheel and get those springs out.
