King coil overs adjustment 2014 Tacoma

I just received my king coilovers and billet icon uca's. Hoping to start the install this weekend. My question is I have been reading around about how much lift i will get out of the preset height of the kings? Looks to come with about 3/4 of an inch of thread showing. I am looking for a 3" lift out of these coils running 285 with this setup. After reading around looks to be next to impossible to adjust them on the truck. Was hoping to get some advise as to how much I should crank them up while they are in the bench mounted spring compressor to make the install and easy as possible.

Thanks for the advise you guys seem to always come through.
