Suspension Mounts - Rubber Vs Polyurethane

[mattross]

My rubber suspension mounts have failed, and the suspension place said it not uncommon in Mk3 golfs why not try polyurethane ones.

Anyone running polyurethane ones? what do you think of them?

[Water Boy]

Polyurethane is stiffer so it will give a harsher ride.

But in saying that the car will fell "tighter"

Exactly which bushes are they saying are worn?

Having been in the VW modifying game since 1992, I am now more than ever, not convinced about polyurethane being the best medium for bushes on road cars.

Upper and Lower Rubber mounts are worn... and compressed...

Why do you say that about the poly ones? Too harsh?

[h100vw]

That still doesn't really say what's gone.

Are they talking about the top mounts, which have the bearings in them?

Or maybe the wishbone bushes, of which the rear one would likely be shot away for sure.

The rear struts have rubber bushes at the top of the shock and inside the car. They get a bit soft looking but I don't reckon you'd notice the difference by fitting new ones.

Poly anywhere in the suspension, is likely to transmit road noise into the cabin to a degree.

I wouldn't but then I have done all this stuff in times gone by.

Is that because of the NVH just affecting comfort or leading to parts breaking?
When I fitted poly bushes in my old Fiat, it was magical to drive, especially on the track, but I kept breaking suspension arms and mounts.

REARS: The rubber is definately getting hard and i can see the line where they used to sit.
FRONTS: same deal, can see a few mil play in them... less than 3 years old too...

I had new rubber ones put in 3 years ago... and now the rear tyres are scrubbing out on the arches (never used too).... handling is also not as good as once before, and i get a little bit of what feels like rear wheel hunting/tracking in a rut???

The VW dealer said he has changes thousands of these and reckoned there is a desgin fault with them and rabbled about a class action against VW years ago because of them.... he suggested polys, so i asked the forum

I was thinking of upgrading to some coilovers with the polys...(or maybe pillow mounts)
The other alternative is to get heavy duty rubber ones (VR6)
