I agree with Dan. Johnny/Polybushings is a good way to go. They will not be cheap, but will work forever. Good idea to get a softer compound.

Write to Johnny @ Polybushings and see if he'll make you a softer-than-usual set of the 2303-2304 mounts.
Thanks SlantSixDan, I'll follow your input.
Maybe a stupid question since I am the kind of person that asks when a bolt needs to be tight, 'how tight (Nm / torque).
What is a definition of 'softer than usual set' and the 2303-2304 mount? I have no idea what that means.

I think Johnny uses 70-durometer material for those mounts usually. Ask him what the options are for a material that is softer than 70. Tell him you want isolation characteristics similar to the original mounts, but the durability and build quality of his polyurethane ones.
