Just wondering, besides the obvious strut braces, roll cages and so on, how to strengthen a chassis?
More specifically spot welding, seam welding and so on?
I will be taking my car to a rolling shell soon enough so wondering what can be done, especially a DIY job?
yeah basically spot weld along all the chassis seams, and then you can use a special resin which is light yet rigid to fill in all the chassis tubing.
see if you can find some stuff on how a lot of the jap workshops do there track cars.
Urethane foam filling.
Where can I get this filler from?
And does it make a big difference? Weight?
Spot welding, is that easy to do yourself?

its got alot of useful info
The foam can be bought online or at any hardware store. As to weight, well it's pretty light. Might be 3-5 pounds per cubic foot and that might be a little high.
Oh ok that is quite light
How does it work for sound deadener then? :)
What kind of areas would I be putting it in?
you put in the chassis rail tubing. of course you have to seal them all off with tape or you'll have a damn big mess lol
Oh you mean under the car??
The foam is light as hell -- :)
And if you are going to spot weld, plug weld instead (Drill the hole, the spot weld it :P)
My 2c
Is it easy to DIY at home??
have you thought of installing chassis braces underneath the car?
