I Like These Stands!
The problem is not at rest, because at that time, they are extremely strong. The problem is if they were to ever tip (too many leaning on the car, trying to remove a part, changing engines, not being level, etc.), the force that causes the stand to bend INCREASES as it bends. That is, when it first starts, the force bending may only be a hundred pounds. Halfway, it may be 300 pounds. But as it gets most of the way, it is closer to 900 lbs. So the danger is, once they start bending, your only hope is to get out of the way FAST!
Many garage floors are not really level. They often have a slope to drain water. It may not be noticable, but rather than have the 900 lbs (3600 lb car/4 wheels) of force in line with the support, it is slightly offset, so there is a bending moment on the support arm. This puts the support in a moment (stress) the entire time until you remove it. Repeated use can then set up fractures (bend, unbend, bend, unbend) and they could fail without you ever knowing they were about to.
Your thin jackstands may look weaker, but by having three dimensions and fair sized ones, they can prevent the bending moments and thus serve a long time without setting up for failure. Also, by not being rigidly attached to the car, the car cannot create a bending moment on the jack stand.
The jack stand problems usually come from overloading the stands or having them on unlevel ground.
The car is a 1969 L-78 Camaro... Burnished brown with a black interior. It had a lot of work done at the same restoration shop that is doing my '69 Camaro. This car cleaned house at the fall 2006 Chevy/Vettefest from what I recall. Very cool car!


For their intended purpose (indoor judged show or display), they are very practical and allow the detail work on the chassis to be easily observed. For actual service work, I would agree with your comments.
As far as safety... That display stand is made from 1/2" heat treated steel. I would be willing to bet that it is as strong if not stronger than the stamped steel jack stands that most people are comfortable using to work on their car.

Those display stands look like a crafty solution for shows and the car looks amazing too.

Easy thing to miss... The hubcap doesn't really show much detail in the photo. I was impressed with your ability to come up with the rear axle ratio. Obviously a real Camaro guy!
This Camaro car is absolutely gorgeous (as are all the cars that come out of this shop) and photos really don't do it justice. They deal mostly with Camaros, but have also done a fair share of Novas and Chevelles... They have even restored a FoMoCo product every now and then. They always have something cool in the shop and I try to stop in any time I get the chance.
