Just had a 2inch (50mm) suspension kit fitted, I understand that I should not need a caster correction bushes fitted on my Patrol 2005 3l, had a wheel alignment and showed castor why out, not sure what all this means but the final measurement is +0 26' +044' so do I need a Castor Correction, Before my upgrade to a 2 inch, afew months ago the caster final was +4 21' +4 42' any help thanks Hutchsky

I know the numbers are in degrees and minutes but what the correct settings are I'm not too sure.
When I was asking around what is needed for a 2" lift. Everyone said I'll need springs and shocks and that's.
I rang around a few 4x4 places and some said yes some said no to offset castor bushes.
I decided to go for a full kit which had offset castor bushes, extended brake lines and a brake proportioning valve bracket. This was recommended with with the spring/shock I chose.

I have also fitted a offset kingpin to help with the camber.

I also was told that I won't need adjustable panhards, but they do hang out a little on the driver's side, well on my gu anyway.

I do believe that having the offset castor has rolled the diff enough so I don't rub on anything with my current tyres, even when I had the 35s on it was minimal on full lock.

That's my input and it worked for me. No doubt you will get different stories.
Do your research and ask around at 4x4 places then do what you believe is right for your situation.

I don't pretend to know anything about this subject but I was also told that I would not need anything when my 50mm kit was fitted. A few months after I noticed the rubber on my drop links needed replacing (not to do with the lift ) and a mate recommended I get extended links. He reconed that with a 50mm lift you extend the links 30mm - don't know why. Anyway I thought whatever and did as he said. Man what a difference to the body roll both on and off road. Also quieter and smoother, but that was probably due to the new rubbers. I also manufactured my own brake equaliser bracket, making it 50mm longer than the original so that the spring sits horizontal again. So hearing that you don't have to change things for a 50mm lift now tells me that , yea you dont have to but it can sure improve things if you do.

Nope, no good to me, just a lot of numbers.
My castor bushes are 2 degrees offset if that helps anyone...

I read that as requiring 2degrees to correct. 2 degrees s not a lot. it really does come down to the car and the driver, some people don't need any correction. I did not do a caster correction on my GQ with a 2" lightened it was fine.

My GU has a 3" lift and i have fitted Drop Boxes which are great. I also have the Kingpin Camber correction offset bearing on the left and rate it highly.

Bottom line is, if you can feel it and think you need to do a correction then you probably do.
