O'k pfofit.I did your tests and the only thing I noticed was there is some movement in the rear drivers side strut at the top.Not allot,maybe 1/8 to 1/4 inch.when I bounce it the metal washer moves up and down on one side.
The washers and rubber are as you show it in your pics.not crushing in or split that I can see.And all is pretty centered.Just the movement.I tried to move the spring but they wouldn't move.I'm not sure 100% though cause you didn't tell me if I had to do this with the car jacked up or not.There are also no cracks or broken spots and there is 2 1/2 inches between the coils all the way around.All the measurements with it on the ground.
And I was wrong about the clearance of the spring seats.I didn't take into consideration they are on an angle.From the bottom lowest portion of the seat to the inner edge of the tire I have about 1 3/4 inch clearance in the front and 3/4 inch in the rear.
Oh and my ride hight is 27 1/2 inches in the front and 26 1/2 in the rear(If i did it right)
