My car is a good candidate to seam weld because I bought it as a stripped shell and it's going the hot rod route anyway. Another Porsche fan suggested the RS America workshop manual regarding how to seam weld the chassis and I thought I should give it a try. to be honest I was a little bit skeptical that the results would would be as significant as they were but here's what I did.

I welded a bar across the front suspension pan suspension points and sat on it with a dial indicator below.

Then I went to town seam welding the front compartment only

I repeated the test under the same conditions and measured a 18% increase in torsionally rigidity over the entire car (I only welded the front).

Cool huh? The whole project is on YouTube

Thanks,
Stay tuned, I'm going to do more A/B testing with the weld in front strut bar. More people might find this interesting.
