Hi Pe, I have the iso mounting system for my MVVS 45, is there an optimum / ideal fire wall thickness? Any pictures of the system installed would be appreciated.

The black rubber tubing that goes through the wall is adapted to the wall thickness by you, so there is not really an optimum as long as the wall is thick enough.
I have a drawing that can be downloaded from my web pages. I am heavily reconstructing the web now. Check out item 3361 under accessories! It is a MSword document.
