I always use a back up system also. And the pins may be the weak point, but look at the pins on regular 3 ton cylinder stands, and the teeth on normal stands, no way I would trust them without a backup.
I did a little research on pin shear, a 1 inch grade 8 bolt has a shear strength of about 70,000 pounds. And it would take double that since there are 2 shear points where the pin is inserted. I am sure this is a heat treated bolt that has close to that shear strength, and enough safety factor built in that a corner of a boxster would be no problem!!
