I have some questions about the stability of this roll bar. It looks pretty,
but are there any test data that indicates in what sort of crash this is not
effective. It just doesn't appear all that substantial to be. It almost
looks like the bare minimum of roll bar strength. The bars are thick but it
doesn't have any back-end support.

It turns out AWR Racing actually builds the rollbar and I have provided
a link to their racecages.com for additional pictures.
http://www.racecages.com/gallery.html  AWR Racing builds the roll cages
for the MX-5 Spec series so they have plenty of experience.  

However, if you really want to see what an MX-5 looks like down to its
unibody shell and the actual rollbar attached in question, then please
visit this link below:


Photos were provide by AWR Racing to look at how their rollbar attaches
to the MX-5.  Note the petty bar for when there is no passenger in the
right seat.  

The beautiful and tight design of the folding top on the MX-5 has made
it extremely difficult to attach any sort of bracing in another plane to
the hoop itself.  The bolt in, bolt out petty bar may be the solution.
