Did a lot of searching on the web about the fitment for spacers and had a lot of questions that I just couldn't find on reddit/forums/YT, so decided to make this thread.
I have a 21' Laramie Sport.
20x9.5 Black Rhino Roku (+12 offset)
King 2.5 coilovers all the way around (25001-209a & 25001-210a)
Ordered Bora .85" rear spacers (adapter) + .375" (slip on w/ lip).
21" Laramie Sport lug length is about 1.5" (conservatively) [exact is probably between 1.5" and 1.6"]. To see if your spacer will fit, just subtract the size of the spacer from 1.5 and that will be the amount of thread that sticks past the spacer. If your wheel pocket is longer than that number, then it should fit fine.
For my application, Black Rhino has about a 1.3" pit behind the wheel that allows for up to 1" of lug to poke through the spacer. That said, I had plenty of space in the back (probably .25" more space - I can fit my fingertip between the end of the lug and the wheel). With a .875" spacer, I had about .8" inches of thread poking past the spacer, that sat within the 1" pocket of the Black Rhino wheels (see pic).
Strange thing about the front is that I had some rubbing without the spacers, but when I put them on, all the rubbing went away. Not sure how to really explain this, but there was initially rubbing on the front wheel well, but it's now gone... so no cutting or trimming anything.
With a .375" spacer in the front, you get full thread engagement (9 full turns, need at least 6 to be acceptable).
Torqued the wheel to 134 (Factory suggests 130).
Rides exactly the same as before they went on and no complaints so far.
If anyone has any questions, let me know... figured I could help some people find some spacers without going too crazy.
*I have Nitto Recon Grapplers, and the sidewalls for these w/ the aggressive side out are about 6-7 mm, so there is definitely more poke with these than with other tires (at least from what I've experienced).
