I am entertaining idea of getting a metal bumpers for the Lexus. Throw a winch on it...things like that. Make it more intimidating in a supermarket parking lot.

Found a website that has the bumpers and other accessories, but it’s talking about stages. Stages 0 to ? saw max 7.

What are these stages? Is it type of terrain? How does that affect quality? Thicker metal? Darker shade of black paint? Heavier duty bolts?
