edit: Have you got any links BV for the failures on locostusa? What's your source for the westield miata issues?

I have long suspected the westfield miata suffers chassis cracking because of solidly mounting the diff, but the sierra diff is solidly mounted and does not throw up any problems.
As said already your design shows you have been thinking about how to mount the mazda diff and the unusual problems its design has created.
Heavy duty engine mounts perhaps rally spec would get the job done.
I came across the problems with westfield miata when I strumbled across the build thread for the car flyin' miata built.
The others including the locostusa came yesterday when I did a google search for MX5 miata diff mount problems.
Sorry I didn't do any links to these sites I was just havin' a beer and surfin'
Well done TQ uk - I like the gold brace on your RX8/Current MX5 rear end. That would be a good way of dealing with the problem, maybe just use the rear 6-8inches of the power plant frame or a lazer cut and folded substitute. That brace would constrain the diff nose and assist the two mounts in the diff carrier.
