Chassis twist, Weak spots Options

[r_towle]

Hi there,

So over the years I have seen all sorts of ideas, lots of products etc..

Seems like we are chasing our tails.

Here is my dilema, and I would like to get some input.

Take a 34 year old chassis, fix the rust.
Add super stiff suspension.
Bearings, bars etc.
add really sticky rubber.

Now, what gives in the chassis...where is the weak spot.
Say I seam weld the suspension console.
What next...something needs to flex, or it seems to me that something will break instead.
I ahve seen pics from McMark of a cracked long inside, and in the miidle of the span..not a rust issue per se, but a fatigue issue.

So, where can I engineer in flex, so the chassis wont crack, or break a weld.

No Cage allowed.
Just the chassis.
Currently there is not inner long kit, or outer...just good repair work on the rust to date...
Nothing is cracked yet...but something will have to give..
I just put in roller bearings....now its really smooth, but now more of the forces are put directly into the chassis...

I think maybe I did not ask the right way.

How can I engineer in flex.
I know it will, and I would like to let it flex, just concentrate that flex to a certain area..

All new tires are more sticky, and not everyone has or wants a cage..
I know the minute I put a cage in, I might as well never drive it on the road again, cause for me, that is the first step into the abyss...the racing abyss.
Till then, why not think of it the other way.

Let it flex, but let it flex a certain way, and in a certain area..
If I put in the engman long kit, and the outer rocker stiffeners, then where does it go...it will flex somewhere..but where?
It is better to let the long flex?
Or move that stress to the fender welds (those would be next)

Im just thinking a little bit outside the box, cause its raining, and I cant drive it...
