3” lift on ORP with KDSS

Hi, new here.
Wanting to put a 3” lift compatible with KDSS. Have found a handful of options, but want to hear some opinions before I make the purchase. Thanks in advance!

 

Fox 2.5 front coilovers, camburg UCAs, rear fox 2.0 shocks with external reservoirs, OMU 895 rear springs.

 

What size tire are you running under that? Jumped the gun and ordered wheels and tires before researching lifts on these guys (was originally going to go with a 4”, or so I thought)

 

285/70/17 on icon rebounds. No rub. No issues. Took off my front mud flap however.

 

Got a 3" Icon stage 2 with 285/65/18

 

3” ADS front and rear, with 285/70/17.

 

Toytec Ultimate 265-70-17 tires.

 

Im going to jump in and ask a question so i dont have to make another thread.. i have 887s and 5100s bought for the tacoma i had, got totaled out before i could install sadly. They will fit a 4runner too correct?

What amount of lift in rear would warrant replacement control arms?

What amount of lift would warrant extended brake lines?(front or rear)

I assume from some preliminary research that new UCA in front are essential with 2.5+ lifting?

Which springrates are what with ome coils, are them 887s going to be too much stiffness for me?
