I don't have the tags on the springs anymore but I wrote down the additional numbers in case I needed them later. The 2967 (rear) had 0815 along with the 2967. My 2969 diesel front springs also had 1215 on them. Honestly, I'm really not sure what the second set of numbers is for. I guess just make sure that the rear really is 0615 and not 0815. I wrote mine down before I installed them (and they got muddy and worn).

As far as the springs go, if I understand you correctly, you are saying that 3 out of 4 aren't sitting in their spring perch. I have to be honest that I'm not even sure how that is possible. Can you post some pictures?

I started out with nothing & still have most of it left

Do you think the JimnyBits caster corrected radius arms for a 3" lift would be better than my current Ironman bushes?

I have no idea how much any of them actually offset so i would not know.

Acc. to my measurements and sketch, the bushings should have approx 5.6mm offset to compensate for a 50mm lift.
anywhere between 5 to 6mm will do the job I guess to better the angle.
Probably the makers choose less offset to retain more rubber on the thin side, i don't know.
I do not remember what mine was or what kind, but they had much less offset.

I could not say if the arm's would be better
I went for the arm's just in case I wanted to go taller in the future
They are a little longer over standard arm's and it has to be better with a bush without a thin side
If you have the money to buy all four arm's and do so you will not be disappointed with the ride feel

I didn't notice that there were other numbers on the other side. I removed and cleaned the tags to get a better view, and it seems like I got the correct springs installed. 2963 front and 2967 rear.

I took a picture but it doesn't show it clearly. Basically, there's a 5-10mm gap between the seat end (don't know the correct term) and the spring end.

Compare this to a spring install I found in YouTube (around 2:51):

OK. The picture is clear and I understand what you are saying. I originally thought you were saying between the bottom of the coil and the base it sits on (spring perch). You are referring to the end of the coil and the rise on the perch. I don't believe a 5 to 10 mm gap there should be an issue or cause the steering issue you mentioned. My brother-in-law is using the Jimny and I will check what mine look like in the morning. Is your Jimny relatively stock except for the OME suspension and caster correction?
