I wish I known this earlier as when I tried using rubber, it just felt too thick and stiff for me to really think it would dampen the vibrations; front studs snapped.
I'm currently using cut outs from an old thick mouse pad I had; will see how that goes when I get a chance to do another good long ride.
So far they felt good when I did a quick test after putting my bike together again to make sure I've fastened everything correctly and it was all working.
