You can never have too much chassis stiffness. Aside from weight, the more the better. Chassis bracing maintains alignment angles and spring rates by significantly reducing body or chassis flex. In fact, it helps every part of the suspension system do its job properly, and you can feel the difference with improved turn-in, sharper steering response, and more steering feedback.
