TOTM: Unibody Stiffening

I couldn't get a clamp on this spot because of the factory shock mount so used a self tapper to bring it flush, worked good.

Xj9140, read the post he quoted - I said both work and noted to avoid brake kleen on things being welded
 
found this in xj9140's thread over in mod tech, and thought of this thread.
I brushed on a bunch of brake fluid to remove the under coating. Scrapes of with a putty knife real easy

I had to cut a another hole in the floor and install a new nut, PITA

I welded in a nut attached to some flat bar (see far left) those other plates are for plating the leaf pockets

The rears complete, still need to finish the rest

Why doesn't anyone make a brace or big skid plate that ties the framerails together along almost the whole length between the tires? It doesn't have to be one piece, it could be 2 that bolt together. Hell, you could connect to the pinch seams too and have a nice flat underside with some 3Dness for more rigidity.

Similar to this, but filled in for protection. BTW note that this Miata has a more protected cat than almost all of us :D

Because you have a driveshaft (or two) and some other things that hang down below the rails. Look underneath with your suspension extended and see where you could tie the sides together.
 
our chassis havent really changed since 2010, so theres not really much to add?
