One upshot I found was that now Yokomo and Tamiya one piece suspension blocks are totally interchangeable. Yokomo's move was maybe unintentional but I have an entire collection of Tamiya mounts I can use on my BD7 and no reason to buy new ones for the 418.

I am sure many other people are in the same boat.

This also means that ultimately one can carry over the entire suspension from one car to the other if they wanted which opens an entire new realm of possibilities especially in part supply challenged parts of the world like mine.

As for the motor mount I too feel Tamiya has left us wanting. The Samix conversion seemed the natural path to go, but perhaps Tamiya still wants to pick some more money on upgrades (or hand over to third parties).

Personally I will probably invest in another Yokomo mount for the 418.
