OK... I'm pulling up a chair...& just put the popcorn in the microwave

Agree that the "stated purpose" is somewhat vague...From the ART Tiger Cage webpage:

"As with any “rollcage”, the main function and ultimate purpose of the TigerCage is to protect the occupants in case of a crash. However, its usefulness is more often expressed in stiffening and strengthening the car’s chassis."

Also on the same page:

"The primary function of the TigerCage is chassis stiffening. Any safety protection is strictly coincidental."
