Driver motor upgrade?

I will check it out, while digging into the silencing blocks, I stumbled onto this Z Axis - Managed to reduce noise a bit seems it does help. I wonder if adding some small o rings or something between the block and cross slide plate could help in a similar fashion. There are also a couple different styles of z couplers, I personally prefer the screw styled ones because they have a bit more give to them and are in general more forgiving, perhaps using those as well could help with the vibrations.
