not to achieve anything other than poly lasts longer simple...
so as I'm going through whole car replacing all bushes and joints.. if there something I can fit polyurethene to (that doesn't have adverse affects) then I will hence asking has anyone fitted them..
all bushes wear.. with age so to say they don't suffer from wear is silly.. rubber deteriorates and thats a fact.. car is 14 years old now they will be perished and less sturdy than new..
if poly don't fit I'll fit nice brand new rubber ones..
I replaced the 14 year old front ARB bushes on my car with polys when I did the wishbones. They were still tight to the bar and the clamp with no visible deterioration. This has been the case with every other car I've seen, hence my suggestion not to bother.
If I felt the need to change them just for the sake of it, I would use the much cheaper(and quicker to get!) stock rubber ones. You could probably make a case for building stiffer droplinks which might vary the effectiveness of the anti-rollbar.
Having spent a fair amount of time under the back of various Omegas(mostly changing wheel bearings), I think your time and money would be far better spent with brand new springs, then refurbing the diff mounts, and maybe replacing the trailing arm bushes(and I bet
they're still OK) than the ARB bushes.
Here's the repair to my broken diff mount curing:
This did make a noticeable difference to the back of the car.
The front end is a slightly different matter; replace EVERYTHING that wears, in one go. That's shocks, springs, top mounts, bearings, bump stops, wishbones, track rods and droplinks. This is mainly because it's so sensitive to setup that you only want to be paying for that once.
