I was recently discussing the poss. of installing a strut brace. A MB member said that, while she likes it, she wishes she had known the drawback:

To wit: you are connecting the sides of the car together. So, a minor hit on one fender can really cause serious damage to the rest of the car. Opinions?

This is not true. (1) if you collapse one side of the car sufficiently to compress the strut brace, you already have serious damage. (2) The strut brace will buckle long before it transmits energy to the opposing spring tower. The strut brace is designed to work within the elastic (non-deformable) regime. When you get into non-recoverable bending, then it will collapse like everything else.

(3) The controlled collapse designed to absorb crash energy is in the axial direction (front-to-back). The strut brace is designed to resist loading in the lateral direction (left-to-right). It contruibutes essentially zero resistance axially. If subjected to an asymmetrical axial load, it will most likely twist around its mounts.
