You can never have too much chassis stiffness. Weight aside, the more the better. Chassis stiffening maintains alignment angles and spring rate by significantly reducing body or chassis flex. In fact, it helps each component of the suspension system do its job properly, and you can feel the difference through improved handling, sharper steering response and more steering feedback.
