These wheels I had are only 15". This is at ride height with the shocks at the minimum acceptable ride height of 13.5" eye to eye. This is using all adjust-ability available in the G-link setup. That is, tilted all the way in on the shock crossmember and the lower mounts in the lowest holes. This is a little lower than some I've seen so I assume it is due to the Fab-9 shock mounts having holes lower maybe.
I'm planning to run 18" wheels in the back so I should get a little tuck at ride height I think.
At ride height. Roughly 1" from rim lip to wheel lip.
This is at full compression. Well, about .25" short of full since the fill tube is currently hitting
