Lower control arm stiffening plates

If that worked the factory bump stop plate would take care of it.

That would leave the LCA with a U-channel configuration. Connecting the sides of the LCA in the bottom crates a box.

Overlapping the flanges the entire length of the control arm adds a significant amount of stiffness to the control arm, and the plate boxing in the entire open bottom does more than just keep the sides from spreading apart- it adds torsional resistance that you won't get from just a few straps. With the straps the area between the straps can still flex and twist.

Shouldn’t be much torsional twist on both ends around the line between the ball joint and LCA. Unless the strut rod is on another arc. The ball joint can’t directly put any twist in the LCA since it is a ball joints that move freely in any direction.

Between the ball joint and strut rod I can see forces that could twist. That’s a small distance with a solid forged tall insert to spread load. Most all LCA I’ve seen, had, and personally bent myself were around the ball joint to strut rod area.

One on left is bent
