Sorry, last thing; in your opinion, would this part be also be appropriate and more importantly, an improvement, on the orignal part? https://www.minispar...black-poly-type
Thanks again for your help.
No. Not an improvement.
poly will not perish like standard rubber ones, and stiffer why do you not consider this an improvement?
It wears out due to in needing to rotate. The rubber ones do not rotate or need to they flex. It has been covered on here many times. I think Spider even included pictures. There are very few places that poly is suitable. The main one, if you fit them the right way round, is the rear subframe. They don’t like heat either so a poor option for the engine side of any engine/box steady.
just because it is new or racers use it does not mean it is any good. See coil springs.
watch some YouTube from poly suppliers and you will see them talk about constant lubrication needs for their bushes.
There is sill good quality rubber one about, there's no good reason to fit polly bushes on a road car, as Nick suggests. I also don't like them as I find them too hard.
good info here, which is why i posed the question. but as minispares ones are at a slight angle and need to be aligned also will the steel tube not rotate, noting the note above and the amount is only small, within the poly bush and the bush just controlling any lateral movement of the lower arm? this was my thinking on how they operate. so poly for crush only? obv. not bumpstops or exhaust
