I estimated the stiffness of my current "big-wire" springs (0.66" wire dia), assuming 8 active coils and an average diameter similar to 5401 and 5413. The guess is 179 lb/in. I also assumed a free height of 13.5"... just a guess.
Because the Moog specs effectively show an installed height at a "test load", a direct comparison of installed height in the same car doesn't jump off those pages.
So I assumed 800 lbs on each spring and calculated the installed height when compressed from the published free heights (free height - 800 x rate).
Here's the installed height ranking I came up with. All make-believe, but maybe useful for "relative" heights and at least feels better than nothing.
