Just found this
Well, I have 881 OME coils ( 2,5" ) with nitrocharger sports shocks on front and before I had 890 OME coils with nitrocharger sports shocks in the back.
Right now in the back is another story: 80 series standart front coils and rear 80 series shocks and I can not be happier!!!! They are way more confortable, very good height ( 3,5" ), awesome flex, when I put weight matches the front, etc, etc, etc.
I'm very very happy with my actual setup!!
Cheers
Reads a little extreme for what I'm after, although a set of well used springs may work very well
When I bought my Ironman 'B' kit it was sold as a 35mm lift from what I can remember, even though everyone called it the Ironman 50mm lift kit. After I'd fitted the kit it did in fact lift the truck an average of 50mm all round, but the standard springs that I'd removed were totally shagged and she was hard on her rear bump stops with even the smallest of loads in the rear.
Still surfing
That came from off of PradoPoint, there's some interesting reading on there and alot of alternative methods used for lifting a 90/95 compared to what we see on here. They seem to be using standard 80 series front springs and 80 series rear shocks to achieve the rear lift and then the same springs that you have J33P for lifting the front with the addition of a small spacer. There's also a lot more talk of the use of diff drop brackets, but then if they are doing 2.5 to 3" lifts youd have to consider dropping the diff to improve the CV angles. There's also some very interesting talk with regards to modified replacement upper front wishbones. I have to say all very interesting reading. I may start to make some posts over there, I see a few from here already do, J33P and ChrisGreen90
Heavy duty metal rear bumper and rear winch time?
Just to make it sit level of course.
One mans meat is another mans poison as they say When I first saw the outcome of fitting the 80 springs I thought 'Blimey!!!', but on reflection I'm now thinking that they look like a pretty good option. Its not that much higher at the rear than the front and I think its looking a tad odd due to the 31" tyres, if you stuck my 33's in that arch and dropped 200Kg in the boot I think that it would look quite well IMHO. And if the spring rate is such that it gives a comfy ride as suggested by others that have fitted the same then it must surely be a win win. The other thing to consider doing would be to cut some of the coil out as with the Calmini springs for the old Zuks. The Calmini front springs where supplied assuming that you were going to fit a winch and winch bumper, but if you weren't then the fitting instructions suggested that you trimmed a certain length of coil out of the spring. This may be an option here to fine tune the lift. The chaps over on PradoPoint that fit these 80 springs also seem to replace the shocks with 80 series rear ones. The other thing that you could do is leave as is and fit the 2.5" front suspension upgrade that they fit along with the diff drop kit
