The nose of the diff rises as a reaction to the road wheels driving forward, the twist on the alluminium diff carrier exceeds the strength of the carrier and it fails exactly as in the pictures NTS posted.
What is needed is a better diff nose mounting arangement to constrain the movement. As said previously, Mazda designed the diff mounts for vibration isolation rather than to constrain torque reaction.
I like the way MNR have mounted the two rear mounts but they do still have diff problems - just view the locost usa site and have a look.

Persactly what I was getting at but it's a package and both ends of the diff need to be fixed properly which also means the chassis needs to be able to take the force. It all needs to work together.
