Disco II better off road?

Disco II better off road?
I had a look underneath a Disco II the other day and was surprised to see new radius arm mountings that look much improved. The end of the radius arm has a tube running across the vehicle that would allow it to articulate freely up or down (no angular movement though).
The trailing arms were the same type of joint, which explains why they are not swappable to earlier Discos - you'd have to put new mounts on the chassis!
From the look of them, a Disco II should have the advantage in articulation becuase the bushing bind would seem to be a lot less.
Could be a good bet to build up a wrecked Disco II? Waddya reckon?

Re: Disco II better off road?
The chassis end of the trailing/radius arms are good IMHO. At the front the radius arm bushes onto the axle are also larger than the D1/RR units so they should offer more flex again with the right setup. On the rear though the entire back end has been done differently to the D1/RR. It is setup with a watts linkage and this setup allows about 10" shocks before you have to hit the watts linkage with the die grinder or start bending stuff. It also has the same bushings in the trailing arms to the axles as what the front has. This means that as you start flexing the bushes start making the roll stiffness progressively tighter. I still think Sam's slotted bushes will allow the D2 to see ramp figures of 1000 (front and rear), though I only know of 1 fellow in the US who has gone and drilled everything.
These pics are of a D2 owner in Melb with 3" lift, about 180lb-Front and 280Lb-Rear, 9" rear shocks, standard front shocks, no drilled bushes. and ACE sway bars.

Hi everybody new user here with my 2c worth,
just read on another site that a stock DSII w/ACE can ramp 731 while a DSII with an OME setup can only manage 560...
Just a little confused right now as I am about to put some sort of a lift in my own DSII w/ACE.
If these figures are true my goal would be to improve or at least retain the RTI of 731, wouldn't you think?

I should also mention the web site I guess...

Some interesting data there and it is pretty similar to what some of the lads in Melbourne (LROCV) have tested on the ramp also. The OME springs are stiffer than the factory setup to gain a bit of lift and are only slightly longer in the free length, but ultimately the stiffness will reduce the RTI. It doesn't reduce the RTI to that extent though. The reason for the big difference on that website is due to the ACE. The one that ramps 730 has ACE, and when the thing is put into low range the swaybars have virtually no effect, its like removing them altogether and so it frees the axle up to move. The other Disco that ramped 590 has the stiffer springs but it also has the sway bars connected which reduces the RTI by a fair bit. If he disconnects the swaybar or runs "Disconnects" he wont be all that far off the Disco that ramped 730. Interestingly that RTI730 Disco has the 18" rims, and with the 16" rims and some tyre deflation it will ramp higher again.
A mate in Vic has setup with a 3" softly sprung lift. About 180lb front and 260lb rear, running factory front shocks and 9" rears 32" MTR's and ramped about 850 with ACE. I would think that with drilled bushes and fitted shocks he wont be far off RTI1000
Anyway, ACE is the key to those stats
