Those are called "speed bumps" in the US, Philippe, and they are very common
over here also, usually in parking lots and parks, where the speed isn't
supposed to go about 10 MPH or so.
I doubt it would add much additional stress to your torsion bars to take
them up a little more - as the weight of the car is not changed, thus the
total torsion on the bar is only slightly increased by asking it to hold the
car a little higher. On the Packard, which uses torsion bars also, it is
common to adjust the height of the car every time the load in the car is
changed, and it can also be changed with an adjustment to the front end, and
I've not heard of a bar breaking yet.
