What corrections needed for 40mm lift?

I had surmised, that all or most kits for bushing s were in the main, tried and tested.

But my suspension numbers and angle measurements was helped a bit by my friends at the local shop so i got a "green" measurement to show the dept of motor vehicles.
In Norway we have to get everything approved.
Sorry i do not have the sketch here at home with the figures, but i can find this at work on Monday.
I do not remember what kinds i bought, but they are all more or less the same offset.
I did not get a steering damper until much later.

I didn't use spacers on the front to level it but my situation may be a little different than yours. When I decided on the OME, I made a special purchase on the diesel front springs (part 2969) which have a significantly higher spring rate than what most people in the PI buy (part 2965). I am fairly sure that my front springs aren't compressing as much as yours. There was still a little bit of a forward lean but it wasn't enough to react to.
As far as the caster correction, I am with the majority that your lift didn't need it. I felt no difference in steering when I went with the OME. That said, since you already have the correction bushings installed, and the car apparently handles reasonably, keep them. In my case it may be that when I went with the OME "40mm lift", I wasn't looking for lift at all. I have steel front and rear bumpers and I was looking to "re-tune" my suspension. As I came back to approximately stock static height, I considered myself fairly successful (except for the front being a stiffer suspension than I wanted). Also, coming back to stock height, my caster angle should be correct.
I also have a steering damper and it did help a lot with our roads here.
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?

Can you confirm the part number that is on tags on the rear springs? Should it have said 2967 for LHD units such as ours? My tags for the rear and front are 0615 and 0715 respectively.
I also noticed a few things with how the springs are installed on my Jimny. 3 out of 4 of the springs are not touching the spring seat end... Should I be worried about this? I noticed that at speeds of about 50km/h, the Jimny doesn't drive straight; but follows a wavy line.

And it's perfect in my opinion steering self centers,rear shocks mount as they should,rear springs do not catch anything
I just fitted a disco 1 damper on own made brackets
Steering still self centers. Only reason I fitted it was the 225/75/16' s I have on now are a little bouncey at 20psi

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

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 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):
