Those wheel ramp things for raising a car

Nice post Kurt... the problem with those two top ones is there's nothing supporting the top part in compression (pushing), the second set has those braces working in tension (pulling) which is useless when dealing with this much force. There needs to be a round cylindrical column of some sort going between the part where the tires rest down to the ground, and maybe one or two smaller ones on the ramp part as well.

Shoot i oughta just make my own none of these look very solid. And i don't like plastic because over time the temp changes and gases in the atmosphere will make it more brittle sooner or later.

EDIT on second thought i'll just get some cheaper stamped steel ones and beef up the hell out of them
