I am planning to change PU or nylon bushes to lower arms of my rally-Felly. I found out that there was last year some group order managed. Well, it is gone but I wonder if someone happens to have dimensions for bushes so I could work ones and the just change them without need to before disassembly old rubber bushes for measuring and keep car out of service . What about rear axle mounting then, what kind of bushes there exist and are they worth to improve?

By the way, has someone changed engine mounting rubbers to solid ones, made of nylon for example? I think rubber mountings are not best option when tihinking about quite violent rally use...:confused: Those should be quite easy to lathe.

i've tried making polyurethane bushes on a lathe and it was a disaster.

i've also thought about nylon engine mounts, but i decided they would be too tough for road use, tufnol may be better for engine mounts..

dont bother with the rear beam bushes, the oe ones are solid..

i've got some bushes here somewhere, i'll measure them up

Thanks Tom again.

There is at least one place in Finland making PU bushes based on customers needs, I dont know what is their method but I don´t care . I´ve heard also that PU is difficult for own lathe but nylon would be easier to work.

the best way to make a polyurethane bush is to mould it in a similar way to making a casting. nylon does machine quite well but you need to modify your cutting tools to get the right finish, also you need to be careful to get the correct surface speed otherwise it will overheat and fuse together.
