Technically it does help. But to get to the limit of a braced vs unbraced car. One generally would need to be on a track and a heck of a driver to even attribute a faster lap time to a brace. Of course it's one of those items that won't hurt to have on your car. I.E. bolt on bolt off no permanent mods. But at street speeds is probably not needed. But they sure look nice and are cheap and easy to install. And if they give you more confidence. Then go for it.
