Seam welding?

I have read many posts about the unibody flexing, but when I search, I do not come up with anything on seam welding. I know a lot of people add cages, but that doesn't work all that well on a DD.

It's not a terribly uncommon practice for uni-body sports cars to be treated to some seam-welding for additional rigidity. Has anyone tried this on an XJ, and if so, what were the results?

I have never heard of this before but I do not see how it would make the structure more rigid. My first thought is, there are not that many seems to begin with. The floor is made of only two pieces of sheetmetal. My second thought is the flex of a unibody does not come from spot welded seems but from the fact that the frame is made from fairly thin stamped sheet rather then a boxed tubing in a regular frame.

if you want to stiffen it up GOOD go get some 1/4" 3x3" angle iron and weld it on to the bottom and outside of the "frame" rails. It'll weight a bit, probably 100 pounds or so total, but it'll help alot to.
