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...

No Cage allowed

there's your real problem ...


the weakest point is the longs right about where the upper windshield hoop is located.
if you plan on running super sticky tires, the only way to go would be a full cage.
the long stiffening kit will help a bit, but not much.

the only other thing i can think of would be a solid roof or at least a solid X-brace under the roof.

short of that, you are out of luck. there's just not enough rigidy in that area without a full cage ...
