This is one of the things that killed foam sedans. Parma sold their Alfa bodies in .020" lexan. They worked fine on all cars, including mod cars. So much so, that it was pretty much standard you had to run that thickness of body. This began the spate of body tucks with any type of contact or improper wheel well trimming.
The bodies can rip but they actually take contact better since they are so flexible. I saw somebody turn one completely inside out, and back again, no harm
