Roll Cages: Chromoly VS. Mild Steel
I'm not saying one way is better than the other really, I went chromo because it was lighter, and the cost was $235.00 more. That's not a much more in my case with the chassis shop I used.
If the welds are good, I doubt you will see any cracking, my car is a street car, and it is just fine. If mine ever cracks, I will let ya know!
