The body, by the way, needs stress. If a lab technician takes tissue samples, isolates the cells, and transfers them to a totally quiescent medium, those cells will die. Systematic application of stress is the way we train, learn and grow. Without stress there is no stimulus. Torpidity, anger, depression, stiffness, and soreness set in as stress mounts because the individual is dysfunctional to start with.
Great athletes are under great stress, but they're far from torpid or depressed or stiff.
The most successful people in any profession are successful because they thrive on stress by way of their functional bodies. The body works from the inside to the outside. The brace is trying to stabilize from the outside in, and it can't be done. I hope not. And even if you could rig up some sort of powerful device to clamp hold of the shaft, the result would be that the guts of the car would be torn out.
