I hate it when people slam my car doors shut, as I am convinced that they will bend and will create wind noise.
Is it bad to slam car doors?
Will it cause the doors to bend?
I have lived under the impression that they will not bend as the entire surface of the door that touches the body would hit evenly at the same time along the entire surface.
If you put a bar at a point on the surface near the hinge I imagine that the door would become damaged.
damage I would worry about
Window components and arms to raise and lower windows
Various clips popping off trim
Locking mechanisms, especially the point of contact with the body.
The window, I've seen windows get cracked from slamming doors and not necessarily the window that's on the door.
