Title: Hmmmmm
Review: For myself, these might work? Only because my car is very small and barely weighs 1800lbs. These are not solid, they are a thinner plastic, maybe 1/4 of an inch thick. They do however stack together nicely to make it easier to store them. I wouldn't recommend these to anyone, not even a Go-cart racer.When I seen RhinoGear I imagined thick sturdy rubber chock-blocks not thin plastic cups.
