but you can get chassis twist, and i have seen a chassis twist completely!!!! not a good thing, not at all... basically throw the shell in the bin and transfer everything to a new shell
what you can do is add another crossmember, weld more metal to chassis to make it thicker, your standard roll cages and stuff
but at the end of the day too much torque for the car is too much torque for the car no matter what... ask your engineer what too much is as they should be able to calculate the max torque for your car... but when your doing stuff like that then you know there is a weely bar required and no road worthiness!!!!
