Suspension Bush Material.
Discussion
I am going to try my hand at making a set of top hat suspension bushes for my bottom chassis>wishbone mount
I am googling around and have come up with a choice of:
NYLATRON
NYLATRON GS
NYLATRON GSM
Delrin
Delrin AF (although I cant seem to get this online)
There also seems to be a choice of cast or extruded rod - not sure if there is a benefit with either type.
Are there any materials I need to steer clear of? Or does anyone one have a recomendations for which of the above to use (or anything that is not on the list...)
Ta!

Picking up on PhillipM's comment that they are more of a bearing than a bush, with a bush there should be no movement between the bush & the metal parts on either side - movement is taken up by deformation of the bush material. If you use a hard material there will be movement between the bush & the metal parts, which are not designed to work in this way & may be subject to wear, as they are relatively soft.
Ok, thanks.
I can see that superflex do Polyurethane round bar that I should be able to turn up into a bush.
The ultima did have the option of a full rose jointed solution, so I am reasonably confident that the mounts will take any additional stress from a nylatron bearing.
(and I have just looked at the web site and they seem to offer a nylatron option now as well)

Unless it's a polyurethane bush in which case there is movement between the crush tube and the polyurethane. They are more like a soft bearing than a metalistic bush. They are also pretty crap IME, the claims made about longevity are massively exaggerated and they have an annoying tendency to squeak.I made some bushes for my Tuscan from acetal with a S/S sleeve. It's harder than poly but not as hard or brittle as nylon. I must admit they do feel hard after the standard rubber type with more NVH but I found I could back my dampers off a click when using them. You will struggle to wear them out either. I am debating going to Poly for the above negative reasons and I do do a fair few road miles in my car but the acetal would be awesome for something more track biased.
