Real Time Help - SPC Upper Control Arm Caster Setting

[Bluetribal]

I have the stock coilovers and UCA out and just put the bushings into the new SPC UCA's and now trying to figure out what caster setting to go with. It has settings from -2° to +2°.
I believe I need to set it to 0° because the control arms already come with 2° off correction to them. Just can't find my notes to verify. UGH!

OK from more searching on toyota-4runner.org it looks like D (0°)

Just for added info I am only up one tire size to 265/70/17
And I am installing 2.5 ICON extended travel front coilovers hopefully set to 2" lift but I forgot to measure stock height prior to putting it up on jacks last night.

I have the same lift installed, but my spc ucas are still sitting in the box. Need to do them soon beaucase the caster is only at .9 definitely darty. I think my hub fender measurement is at 22.5” after lift. Still need to adjust out the .5” driver side lean

Caster that is stock should be +3.28ish. If you lift you need to get more positive to reach that stock number, and a little higher makes it steer well. I currently run around +4 caster on my GX.

Got it all buttoned up but at full droop the ABS line is really tight! Not happy with this.

Plus I broke off the bolt for the bracket in the new UCA. Should have used my little 1/4” wratchet instead of my 1/2” wratchet. Tried to drill it out but no way to get that control arm flat on the drill press and ended up drilling it out crooked! This killed an hour today and I will have to clamp the ABS wire bracket now on the DS.

What spring you running? Lots of preload.

Not sure, I picked these up used and re-built. The spring says 158504 on it and it came off of a Taco.

*Update*
Couldn’t find any specs for the springs used on thes coilovers from the website.

FYI you will need a 1 1/4” socket to tighten up the adjustment nut on these SPC UCA’s. Just got back from Lowe’s where they sell individual 1/2” drive Kobalt sockets.
