I am puzzled when you say that the poly bushes aren't as good as the standard bushes; I rather thought the opposite is true. Poly bushes certainly wear much better than the rubber originals. Even if they are no better in performance terms; they don't wear out and will therefore maintain a constant level of performance, unlike the rubber originals.

Some cossie's had roller bearings in the arms, but these can seize up/wear out, then it is much easier to put poly in, but some purists like originality on a extensively modified cosworth, no I've never been able to figure that one out yet either!!
Absolutely nothing wrong with poly on all the points, a poly bush will give a vastly better location than a shagged sticking 20+ year old roller bearing.
The std sapphy suspension design is shit, that's why they self steer at the rear, made a lot worse with soft location from rubber bushes and the badly thought out diff hanger.
The sierra doesn't use trailing arms further adding to the problem, as the arms are semi trailing any upward movement of the wheel causes not only a camber movement but also a toe movement.
Poly bush the lot, then add a poly diff hanger, or you can get the std diff mount poly filled for Ł20-Ł25, these seem to work just as well, and look more ford like for the bufties.
It really will transform the car, then add a 22mm roll bar it really is a totally different car, you will get a fraction more vibration but nothing that you don't forget about as it's so minor, but well worth it for the tansformation, ford had to use whatever they had in the parts bin so that's why it wasn't as good as it should have been.
I didn't want to get ripped off with a escos rear arb(22mm) so had one made 22mm and adjustable for less money, and it clears my tow bar bracket.

I have just ordered a diff mount from MSD; so that will go in with the poly bush kit.
The interesting thing about the poly bushes is that the Superflex product, and some of the others, are all made in Australia (in Brisbane). I have contacted the manufacturer and they'll sell the parts here, but I can't work out which parts nos. make up the kit.

A mate made it for me for Ł80, the trouble with poly is comparing all poly as equal, it isn't, amazingly a different COLOUR will made the hardness different even with the same mix.
Mix up a pot of poly pour into 4 different pots then add different colours to each, the hardness will be different, different brands of colour will alter this further.
Some poly bushes I have used have been massively too hard, Superflex, which is as said aussie made by Pro Sport makde ace bsuhes apart from the beam bushes, the vibration is mental I found.
The best beam location from beam bushes I found was std bushes with GGR axle tightening kit.

with new org.Cosworth roller bearings, you get a greater movement on the arm, so the shocks can do their job. same case whith a motorcycle, a expensive shock do not help if the Swingarm are "stuck" in the frame??

Mr T you would fit new trail arm bushes along with the rest in a poly kit
poly's on the trail arms have an adverse effect on the feel/drive of the car on the rear, they are just too hard imo Luciano

And you are entitled to your opinion, but you are the first I have known have a negative opinion, as for some very ignorant of the qualities of poly person saying they get stuck, f**k nearly pissed myself laughing, sorry but the major adavantage of poly is it is SELF LUBRICATING, the only bit that gets stuck is the metal insert where used.
They have been used in the outback of oz for over 25 years where component failure can mean DEATH due to the sparse nature of the country, they wouldn't chance anything less than 100% proven reliable.
I have coilovers, run 300lb" front and 200lb" rear with poly on anything that moves, and it is still very comfortable, even if it wasn't it would still be worth the handling improvements for it.
The diff hanger gives more vibration and noise, but I don't hear anyone saying they've taken it off because of it, if you want a comfy car buy a citroen, if a performance car accept that there will be downsides.

I need someone to spell it out for me.
I should order a Superflex kit less the rear beam bushes?
I need a GGR rear beam tightening kit with replacement OE rear beam bushes? (do I still need this with my soon to be fitted MSD diff mount?)
Do I have that right?

Having used SUPERFLEX myself, this was my view about the bsuhes, all are ok apart from the beam bushes, seriously too hard, was taking me poor little xr4i a load of power to try to drive through the vibration.
You might as wel try and save a bit with your local and try SUPER PRO, they are made in your country after all.
My sapphy has poly beam bushes that were on it when purchased and they are not too hard, not sure of make though 99% sure it is deflex, or floflex as they are called now.
I don't think many peeps tried the GGR axle tightening kit as it seems expensive for 4 bits of nylon, but certainly when I used it, it worked brilliantly, with escort cossie beam bushes.
Even with poly on the arms etc, the up down movement of the diff will take place, so yes still defo need the poly diff mount.

r2d2,
Please accept my appologies, I think when re reading the wording that I was very critical of you for no reason, and ask that you forgive me for this.
I tend to get carried away some times, and as I have brain damage this does lead me to act innapropriately times, without realising at the time.
I put this on the public domain as I consider that it should be, I am, sorry.

No hard feelings. I don`t mean that i know best. If my english was better, maybe i would write it different, but it`s the best i can do next after writing Norwegian. I mean to use new org.Cosworth roller bearings was my choice, most because of that i modified the rear beam to allow fixing bolt from Mondeo so i could adjust camber and toe-in a little bit without loosing the look of orginality, and the org.Cosworth roller bearings allow that movement on the trailing arms better, i know it`s better ways out there, but i was trying to hide away the "custom job" on this 86mod RS Cosworth, and i felt that the improvement was great, even on track-days with little to soft springs (no coilover just Bilstein dampers and Eibach springs)

I've often though about putting eccentric adjusters on the mounting points for the arms, but don't know if the small amount of adjustement these will give would be enough.
Have you measured the before and after angles etc ?
What sort of difference do you find ?

Some people don't want to poly bush everything as it can make the car very harsh.
Personally i've got solid mounts on the beam and the rest is poly bushed. The car is very harsh but also very positive. It suits what i want from the car. Which is essentially fast road and track. On the other hand it can be a real handful in the wet on bad roads, due to the stiffness.

It depends what you want from the car.
