I had an old International Travelall that I had lowered, a bit too much. It rode on the bump stops in the front. My dad rode with me and let me know that it wasn't good and I should raise it back up. I thought, meh whatever old man. About a week later I went over a speed bump real slow and the steering wheel spun in my hand!
I had been bouncing through Seattle streets on that stop and it had stressed and eventually ripped the lower control arm mount from the crossmember.
I think it would've been fine if I had a shorter bump stop. The way it was set up clearly wasn't right. Not trying to scare anyone just letting you know what I experienced.
