In this case it's not the type of rubber that makes the noise or gives the vibration.
It's purely the stiffness.
I also wonder if normal rubber handles heat better than PU. Both materials don't react too good to heat. Also not all rubber is made equal.
There has been a case of VT mounts here probably fail due to heat. And those arent PU.
That person later switched to bimmerworld mounts, but reportedly those are considerably stiffer than VT ones and give more NVH feedback.
Nice thing about those powerflex ones is that you can regulate the stiffness. So I think they have the highest level of engineering.
No hands on experience though.
That'll problably come when my VT ones need replacing. But so far they still hold without a problem.
Too bad those powerflex ones are so expensive.
