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...

Crap thats symple! No role cage is no big deal. All is required is thingking out side the box or should I say inside the box.


One can stiffen the car and still have it completely STOCK looking. I've been thinking of this for a while and have come to the conclusion that if the boxed frame longs were used more as a hiding place for a DOM subframe which would tie into all the so called week links of the unibody, it would be the tits. The longs can be cut open underneath, gutted, beafed up and recaped; welded back to their original spot.. You also need to remember that all vehicles are designed to flex which is very evident on body over frame designs as well as many unibodies. It all depends on what you want to accomplished which kinda sounds like something which the car was never originally designed for; much like the rest of us who beaf up the suspension and add role cages.

Admit your sick like the rest of us and do what you want. My sugestion is if its a beater then go wild, if its restorable please, don't bastardise it:beer1:
