I was just wondering is any one has looked in to ways of stiffening the chassis? Yes I know you can add a roll bar or cage. More looking at the frame to help reduce flex. No you may not feel if yet it is always just around the next corner.
I was talking with a shop who welds in between all spot welds. At first I was like a total waste for a older 60s car. How much does it really help?!? After my short hard drive I need to remove my foot from my mouth.

Like I mentioned just wondering. Ok maybe no one has thought of it.

Thanks for you thought and input

The stitch welding you saw is widely used on unibody cars, mostly around shock towers.
On a body-on-frame car like the roadster you bring a up a great point of debate: does the frame distribute it's stiffness through the body?

14 bolts tie them together. Short of a roll cage that ties the body/frame or more x-braces on the frame I can't think of anything else. Plus, more braces = more weight.

I always wondered if a cross bar or x-brace behind the seats would help.

I know that "Down Under" they weld in a brace just the engine side of the firewall and another in the trunk to help keep the body from flexing as much.

I don't know about stiffening, but I have seen people install front hoops when they remove the inter-fenders. I was thinking of welding the body to the frame.
