I'm not buying the heims rationalization. I don't like mid unsupported bends in tubing, I don't like tube braces that do not share a node at their termination, I don't see why the relatively thin sheet metal inner fender needs support 4+" above a the nearest suspension point, I don't know how much stiffness an attachment to the firewall provides mid center panel, and I haven't needed to see any numbers/calcs/testing to make the above claims. Haven't heard that torque boxes are little improvement before, which I agree with totally and have postulated for years once frame connectors are installed. But people like to add stuff under the heading "it can't hurt".
