From what I surmise from the installation pictures you are removing a steel brace which seems to have bends to create strength that was installed by Toyota and replacing it with a solid heavy powder coated steel brace. I would almost guess that the stiffening brace supplied by Toyota was doing it's job just as well with half the weight.
It looks like you've been on the board long enough to know that what you posted is just not true. Why did you do that?
