Thanks for all the help on the mounts. As far as the aluminum standoffs most people that seem to have problems do not realize that they really shouldn't tighten them up against the typical firewall without something to spread the load and stop them from being compressed into the firewall. This creates a condition where they loosen against the firewall or weaken the hard point through it. The end result is always that the engine vibrates and torques putting a lot of stress on the tabs, the firewall, and the airframe.

I typically use a sandwich of at least 1/8" birch ply disks on both sides of the firewall and fender washers. This makes it so the ply doesn't compress and the torsoin loads are not reliant on the 1/2" diameter of the standoff. I don't rely on fender washers alone since they tend to concentrate the load on the center of the washer.

This thing looks like it would be a pretty good match for the Aeroworks Ultimate or Python. What do you think?
