There is no rubber or poly so expect them to be very harsh. They will be fine with any up and down wheel movement, but any wheel motion fore/aft cannot be absorbed for with this type of design. This is the type of motion the wheel sees when hitting a pothole, manhole cover, speed bump, etc.

Now if your car is a "track queen", there should be no worries. But on the type of potholed roads we have here, the spot welds on the chassis would be popping out after a short drive.
