FZJ80 Caster issue

So today I installed my OME caster correction bushings. I took my time, did my research and installed them the correct way so I know that isn't the issue. My caster is still way out and Im quite frustrated as to why its still in the negative. My pinion angle appears to be even worse after the bushings were installed as well. It still tracks almost perfectly straight though and I get very little vibration or growling from the driveshafts. I'm moving from Atlanta to Boulder CO in two days and I was really hoping to have my alignment as close to spec as possible before the 20 hour trip.
Specs:
97 fzj80
Ome nitro charger shocks installed 6 months ago
J springs in the rear
(not sure of the springs in the front, po never told me) 2.5 inch lift
Brand new 285/75r16 mt r's
38mm spacers

When the previous owner installed the springs he put them on opposite sides but I highly doubt it would cause my caster issue.

Alignment sheet:


Any and all input is welcomed!

Thanks guys.

You will be much better served with caster plates.
With J's front & rear you should have a stinkbug look?
What is the measurement from the center of your hub to the lip of your fender well F & R?

What Phil said.
I did the busings with my OME lift and it wasn't enough. Go with plates or arms. Did plates with mine and it made a world of difference

I'll echo the comments. If you have over 3" of lift (say matching J springs in front) you certainly will benefit from caster plates.

There are a couple of other options, we also stock a 3* caster bushing set. But remember, for every degree you improve your caster, you will turn down your pinion.

Another neat option that is new'ish to the market, caster knuckle bearings. If by chance you need to do a knuckle overhaul, seriously consider caster bearings at the same time. This give you the best of both worlds, increased caster AND leaves your pinion in place for better pinion angles. Available in 1* (that can also be used for camber adjustments) and 3* which is killer for a 2-3" setup.

Awesome! I will look into that. Thanks for the heads up. Dropped by Slee since its only 20 mins from my new house. Talked to Cristo and he confirmed I have 850's up front and some 3inch tjm springs in the rear. SOO my lift is too big for the castor correction. Trying to acquire a used 851/860 setup. If I don't have any luck soon I will be trying some of the ideas y'all presented.

Thanks for the input guys.

Kurt, since I'll be pulling my front end apart again soon to change the R&P it could be a good time to make changes to caster. I've already got caster plates, but would it be helpful to also consider the caster bearings to replace the trunions? Just to refresh your memory on my setup. J springs all around, 1.5" spacers, L shocks. What say you?

TIA

It very well could. Before you pull it down get an alignment reading so we know where you are at with caster. Plates are generally 3.5-4* which is good for a 3-5" setup. You're pushing the end limits of that range.
