Outstanding. I have been griping for 2 years+ that the 80 stuff on the market has the wrong bias entirely (up travel). The FOR kit was designed to address this to a degree, but you have gone a major step forward in fitting 37's and engineering the 1/3 to 2/3 travel ratio (a rock crawler's ratio for sure

)
Still, though, how are those coils giving you 7-8" of droop without coming well off the tower...or are they and you have restrained them? The front I can buy to a degree, but the rear on the 80 is extremely difficult to get the load bearing in the coil rate while also designing a long travel suspension focused largely on droop. Even at 5" of droop you are pushing the limits of keeping a typical 3" coil (250 lb/in or so) seated.
I'm just asking because I'm curious as the spring rate to travel issue is the primary factor in achieving this design balance (rock crawling travel ratios while retaining load bearing on a very heavy rig). My up travel is nearly identical to yours, but you have 2" more down (I'm 50/50 accordingly). I know I could easily run 36" tires on my setup, but 37" would be pushing it even without flares and I'd have coil problems with 2.5" more droop in the rear for sure.
What shock valving have you dialed in if you don't mind saying? Geez this gets me thinking at least 36's...good thing I did those 5.29's
