22005 4Runner Suspension Upgrade In Progress

[Clarkson!]

Hi everyone, I am in the midst of my first noticeable upgrade to my recently acquired 2005 4Runner. This past weekend I installed Bilstein 2" lift springs in the rear, SLEE offroad steel braided brake lines, and Bilstein B5100 rear struts. This has given me exactly 2" of lift in the rear.

This next weekend I am replacing upper control arms, rebuilding lower control arms, replacing tie rods, and installing Bilstein B5100 adjustable struts. It looks like the previous owner put FJ Cruiser springs on the front based on the colros and the fact that they appear to have raised the front about 1" from stock. My question is, if I set the B5100 for 2.5" lift, and re-use the FJ springs does this mean I will get a 3.5" lift up front? If so, will I run into other issues and be better off selecting the 1.75" setting? I am upgrading to JBA high caster arms, but am unsure what else may be an issue and would like a heads up before I get too far into it. Thanks all for any advice you can provide, Here are some pics of this past weekends upgrades.

I don't have bilsteins myself, this is just from some research I've done when looking into them. Hopefully someone with first hand experience will chime in: I'd avoid putting the front bilsteins to 2.5" and then using the 1" coil. Bilstein recommends that with any lift coil they be set to the lowest perch. I think you could get away with setting it a little higher like the 0.85 setting, but I'd avoid the very top perch

I have a writeup on the LCA rebuild, shameless plug: Whiteline Lower Control Arm Bushing Tutorial (120+ Pictures). Let me know if you have any questions with the rebuild!

Thanks for the info. I've been trying to find some instructions from Bilstein but have not had any luck. Was thinking of going to 1.75“ up front as I think that will come close to leveling the 4runner. Do you happen to recall where you found the recommendation to stick to 1.75 on the strut? Thanks!
