You gave no dimensions or otherwise allowing for any help. Your question
read as if you were ignorant of the basic physical facts re. your "problem".

Thanks for the non-help - since when does Young's Modulus address fatigue
factors in typical mild steel - which was my question? Not in my
experience.

Do some study on Young's Modulus (Modulus of Elasticity).

I have an anti-roll bar from a Formula Ford race car that has suffered a
bit, and has a twist. It's obviously not up to it's original use in a
mild steel spec, but I modified the suspension design somewhat and it
will not see nearly as much potential twist in use. What I wonder is can
I simply twist it back into alignment, either hot or cold, and have it
perform pretty much as it did before it got twisted and then untwisted?
I can't see why not, but I have cumulative fatigue factors in mind that I
don't know about.

My thought is to replace the ARB with a 4130 heat treated version , but
I want to drive the car first to see if the bar rate is close to right.
Then, I'll make up one with the correct rate in the correct material.

Thanks, Brian
