To much lift! (Is there any such thing?)

Thanks guys. My coils have a free length of about 480mm front, and 540mm rear (quick measurements). So it sounds like it could well be the same items. Thanks Lambrover for the pics, I am measuring mine the same way, but from the front of the bump stop. I would think my BSC from your measuring point would still be closer to 180-185mm? I assume that is the rear you have attached a phtoto of, sorry the ruler is a bit blurry, but it looks like you have a pretty impressive BSC there as well....... I can try to replicate the lift (coils back out now) tomorrow.
Good point about unseating the coil, that isn’t something I had thought of. However, surely if the shock is at maximum extension and the coil stays put then thats that? The opposite wheel articulating could change the angle of the mounting plate on the diff a bit, but not actually vary the length the coil is at by very much surely?
Either way, I have taken them out now, and have a “long and low” 110 in the driveway again until I get this sorted out. :(
I have just added an album on here with some photos of the 110 with the coils in. Sorry but I’m not sure how to post them directly on here (searching that now).
My tyres are 7.50 x 16. The photo of the coils next to my old black one is of the rear coils. After a clean up, I found some orange and green dashes on them, so I would assume they are LRA orange/green 320 lb springs. Original free length of these is supposed to be 426mm but mine have sagged to about 400mm.
For anyone else with a Defender this height - std exhaust will hit on A frame (at ride height, let alone on droop). :(

I am really waiting to hear back from the seller and Dobinsons to see what their thoughts are. Good to hear that Lambrover’s coils were that same free length, but I must admit I was hoping mine were longer to start with (as in – wrong springs in the box or something). To me that says my car is either a fair bit lighter than yours, or the rate is quite different?
Bracing for a big feed of humble pie here, garnished with 'you've stuffed this up Pat' hence not naming names.... Fairly well decided that is this amount of lift IS 3" then its more than I was expecting / prepared to do properly at this stage anyway. Lesson learnt. :blush:

I must say its quite frustrating that getting answers from manufaturer and supplier is very "when I'm ready you'll get your answer", where as dealing with UK companies regarding arms etc has usually been an overnight response (but lets not go there) :angel:

Cheers for the input guys, its really a big help.

with that much lift rotating the swivels is a must to return the castor....but your axle roll axis is going to be high oversteer front and rear meaning that bump steer will be high as will squirliness on uneven cambered roads.

I had wondered this myself, I put the front coils in with the closer coils at the bottom (as this is where the close winds were on the old coils - and they had about 4 touching). But I am not sure it would reduce the height by much flipping them over?

Good info regarding roll axis. A question that came to me was that if I was to go with slotted swivels (I am walking away from this lift now - so its hypothetical), would I need to put a wedge or similar under the bottom mounting plate? As having an uneven base at normal ride height can’t be good for the coils or accuracy of height etc etc ?

So you are usnig stock raduis arms and no castor bushes at the moment? What about rear arms? - interesting to hear that.......

Yeah mate I am using stock radius arms and standard bushes. I have cranked rear arms. Lowranger has really good rear arms, I think they are Gwyn Lewis ((spelling is most likely wrong).

With regards to the angle of the bottom spring perch, don't touch them. As the axle travels up the axle rolls back and the perch angle flattens out, our spring won't fall out, mine are like now and so was my last car.

My coils were made for my old 110 county with the Isuzu engine and dual wheel carrier on the rear, long range tank and draw system, bullbar and winch. When you ordered your coils what did you say you had fitted, it sounds like you have some for a loaded vehicle so the spring rate is to high for your empty vehicle.

I did say it was fitted with drawers, and a LR factory bullbar (ARB style). I asked if they needed to know weights or for me to run the car over a weighbridge etc. I am sure I didn't give a weight, just a quick outline of the stuff bolted to it. I was amazed they could order springs based on this (they never saw the car), but I figured my 110 is hardly exceptional in any way - and they must know what they are doing :( certainly no Isuzu under the bonnet....

By the way: my Deefer is standard, with some big draws (full length and up to the tub depth), bullbar, tune side steps, rear bar (made from factory front bumper), rear wheel carrier and that's about it. Got diff locks and a few bits and bobs but nothing extra weight wise..

Not knowing exactly what you are trying to achieve with your setup,makes it a bit difficult to make too many recommendations.But if you are only going to run up to 33" tyres,then my serious recommendation is that you swap the springs you have for something that gives up to 2" lift. Using the springs you have is going to require a lot more mods and money to overcome.And it sounds like you are dealing with the same company I did,when I bought my original replacement springs,they don't like to give away any information,hence part of the reason I will never deal with them again.I went and had the corners of my vehicle weighed when in normal loaded mode,and bought the appropriate springs to match the weight

Wayne is right, what are you going to do with the car?

With regards to coils and who's to use, not sure. Wayne's current coil set up works really well and he has a little less body roll then I do.

Hay Wayne what brand are your coils.
