Notching up the stock worn out coils with the 5100s made the ride too rough. New shocks and springs make it ride awesome!

I have this setup right now. Very happy with how it turned out.

OME 883 front
Wheeler T13 rear
Bilstein 5100s

Hub to fender 22" up front and 23.25" out back.

Sitting on the same 265/75r16 Falkens.

That looks really good. But wouldn't stock springs be softer than OME?

OME 883: 375mm in height, 590 pound spring rate​
OME 884: 390mm in height 590 pound spring rate
OME 885: 395mm in height 590 pound spring rate
OME 886: 402mm in height 660 pound spring rate
OME 887: 400mm in height 590 pound spring rate
​​OME 888: 405 mm in height 590 pound spring rate​

stock is... 580?

Just purchased the Eibach stage 1 prep truck lift kit. It doesn't come with rear springs and am looking to improve from the 155k mile original rear shocks. I've been reading fj could are quite popular, but what if I wanted an extra inch lift in the back. Or do those fj coils give it over the stock springs? Trying to figure out the best rear spring to swap in for the oem. The fronts can be adjusted up to 2.75" while the rear shocks are firm at 1". Would love some input from a newbie who just ordered his first mod. Thanks.

FWIW, the suspension post linked in my sig has a pic of FJ springs side-by-side with OEM springs. Scroll to the very bottom. In my case, the FJ springs added about .25” of height.

Yes, by 2% (590 vs 580) But using stock springs notched up with 5100s puts a pre-load on the spring, making it much stiffer. Whereas you can achieve the same lift desired with new springs without putting a preload on the spring.

End result is that the stock springs would in fact have a higher spring rate with that configuration.

If you just want to lift the front to level it out on the cheap, go with a top out spacer. Won't change the ride quality.

That is exactly what I would like to end up with.

But, i'm not sure what this means: "Notching up the stock worn out coils with the 5100s made the ride too rough."

Right. I was just wondering if there was a spring that would give me another inch over FJ's to give me a 2inch lift in the rear.

Amazing how just a few words from a stranger on the internet led me to an instantly lighter wallet. Just purchased some 883s. Ugh thanks!

The Bilstein 5100s let you adjust the front ride height. 4 settings, stock, .85", 1.75", and 2.5". This is done by adjusting the bottom spring perch. In reality this is putting a pre-load on the spring by compressing it, similar to some spacer lifts (when the spacer I'd on the spring inside the strut vs top spacer).

Hope that helps.

Wheeler/Eibach T13 gave me about 1.25" lift. The T12 springs give about 2-2.25 from what I have read.

Gotcha.
I would think your on the verge of needing them but honestly if I was in your shoes I wouldn't bother with them at first. Get the lift on it and and see where your alignment is, you may be marginally ok. You may have to go back in and do the uppers.
If your lifting with springs you have to get longer shocks, no way around it that I'm aware of besides ridiculous work.
Spacer lift will just go in and work with what you have shock and spring wise. Not sure if you can get a full 3" front spacer lift though.
As far as kits go there are many available. Get something basic, no need to spend 2 grand on resi shocks if your never going to need the cooling performance when a standard tube style will suffice.
People love getting the best of the best when in reality the best of the best is so far above what most average people really need. I can get a 5 thousand dollar fly rod and a 500 dollar rod. I won't really be able to tell the difference between the two of them and a 200 dollar rod has all the performance my skill level requires for now.
Food for thought?
I know that doesn't help you with brand specifics and stuff but it may help to steer you in a good direction hopefully?

Have a 2003 4runner v8. 253k. Recently just "upgraded" suspension with 2016 tacoma set up and new coils in the back. Took her in for an alignment. The shop suggested i get a new car. cambers and caster are to far out to do it? What should i do? I mean i have a manifold leak.

Front -0.04 total toe

Steer ahead 0.21

Rear -0.10 total toe
Thrust angle 0.06

Not sure what these mean.
