LCA Reinforcement Plate

Even the sissy little factory swaybar put a twisting force on one side of a lower arm assembly. If I were going to install one of those huge aftermarket swaybars I would definately want the reinforcement plates welded on to transfer that force across both sides of the arm.
From what I've read, those retail plates arrive flat and will need formed to the contour of the arm during install. I dont know why short pieces of flat bar welded acoss in a few places wouldn't serve just as well. An opening for the adjust bolt ofcouse and an opening at the bottom for rocks and mud to escape is all to factor in.
