Lifting my disco
Guardian.:
2 inch lift does not need castor corrected arm etc, i have lifted plenty and they dont really suffer on the steering at all, not that is going to be a problem, infact due to new compnents fitted replacing knackered old ones it is actaully an improvement on wht you were happily driving before you lifted it.
plus when you start rolling axles about it just [!Expletive Deleted!] up the props big time, so then its more expense on flash props with double joints.
all this said, if your off doing some crazy stuff, then you do need more of the kit, but you will be probably lifting more than 2 inches aswell.

My problem with liftin motors is that you dont rly gain that much, sure your chassis is lifted so yo may not belly out as much but you have no more clearence under your diffs which is the first thing that you normaly fet hung up on, and you rase the COG a fair but too.
If you fit bigger tyres you get more under diff clearence with a chassis lift aswell.
Ok so i'll probably get shot down in flames here by people saying that you will then rub the arches but surley then cutting you arches will not take that much longet than fitting a lift kit and its a dam sight cheeper. If you go from 205's to some 235/85's or 265/75's then you will get nearly a 2"lift anyway.
Just my opinion.

Muddy, it can depend on your stiuation.
I lifted my RRC to improve departure and break over angles, which it has done. £200 on new suspention compared is a lot cheaper than new bigger tyres, though I have since fitted 7.50 SATs which give a very noticeable improvement in deep ruts.
You will always find that no matter how much you modify you vehicle there will be some obsticles you can't pass, but know with a few more modifications you could. The sky is not the limit, just how much your prepared to spent in time and money.
skiprat:
i have a 2" lift on my 300tdi, brought my kit 2nd hand from a friend (so i know its history). orange springs and de carbon shocks. running slightly taller tyres (245/75/16's). and it handles better than standard.
good luck with what ever you decide

People....
Let's not generalise. The comment that a 2 inch lift does not need castor correcting arms is absolute rubbish.
It just doesn't work like that.
Are we talking lifting a saggy old suspension by 2" or adding an extra 2" over a brand new set up?
What decides WHEN you need or don't need the castor correcting arms?
It's nothing to do with the amount of lift. It's down to exactly what the castor angle is. There's inbuilt tolerances to be worked with to start with.
AIUI the Castor angle should be 2 to 4 degree on a Discovery.
So if as standard you have 4 degrees to start with then a 2" lift could (note could) take off 3 degrees. So you're left with 1 degree of Castor.
Not ideal but reasonably usable.
Start off with 2 degrees and add the lift and you're left with -1 degree.
The closer to 0 or a minus figure it goes the worse the effect on the steering.
Most people that have castor problems don't even notice the problem is there. Get the definitive answer and do your mods and then get the castor angle checked. You'll find your in for a shock and a lot more expense.
New castor correcting arms.
New Cardon prop because the diff is tipped an an angle that straightens out the front UJ.
It goes on and on and on.
Don't start me on brake hoses. Anyone seen a standard Disco with the rear axle hanging? You can play a tune on the hose.
