Tony,
Personally I would not bother. The standard instrument panel is quite flexible
anyway, to the extent that a g-meter installed in mine gets 'flicked' to stupidly
high readings on a hard landing as the panel rebounds elastically. A resilient
foam gasket under the panel mounting flange may provide some useful damping.

Hi Tony,
Whilst building, like you, I considered some of the MODS to dampen the vibrations
of the Control Panel. However, I decide to follow the instructions from the
original build manual, and I am glad that I did, as I have never noticed a problem
in the couple of years my aircraft has been flying. Obviously some pilots
have had a problem (hence the MODS), but it has been my experience that it is
best to build the aircraft as designed, only making changes when experience
has proved them necessary.
I have attached a couple of pictures of my panel, one showing the attachment points
during the build, and one of the finished article.

G-LDVO BUILT AS PER MANUAL NO RUBBER INSTALLED AND NOT HAD A PROBLEM IN 180 hours
FLYING.
