the reason not to use hard bushes is that there are alot of forces in all directions on the suspension so not only up & down but also forward & backwards & so if the bushes are too hard all that stress & force will go to the welds .

Default question to flyerncle re bush material.

Hi there,
reading your reply on the bush material subject and would like to know what the UHMWPE material stands for and is it as good as poly bushes.
cheers

Cheers Ronnie,saved me trying to remember/work it out.

Neoprene is soft so possibly not good for bushes.
With regard to using hard bushes I understand your concern that passing more forces to the weld/structure may cause failure, but on the other hand what about the use of Rose joints as they are more or less solid.
Personal opinion on bushes, I have used the best/cheapest/easiest solution to the problem and it will do what I need it to do.
A certain amount of give in the bushes will lessen feedback from the road ie bumps and the like as this will not be fed back through steering and suspension, I think I have read that poly bushes are abrasive and the stainless tubes were sacrifical/meant to wear, so I suppose it all depends on what you want from the car and how much time and money you want to spend.
Please do not take any of the above as argumenative it's only my point of view and there will be someone on here who can give the definitive solution.


Cheers All

UHMWPE = Ultra High Molecular Weight PolyEthylene

Neoprene is more than likely far far too soft for bushes - although the only neoprene I have dealt with is in Diving kit. (as an aside - neoprene is generally made by injecting nitrogen into rubber sheets)

To Flyerncle - I assume that it is only the SS tube that is meant to rotate inside the bush. Otherwise given (a lot) of time surely the outer wishbone bush tube would also wear??

I personally think, that in terms of wear, the mileage we do is probably inconsequential. A lot of rep-mobiles are doing 50k a year, how many roadsters are doing more than 10k??

Again, not trying to start a ruck, just furthering my learning

Sean
