^^ Care to explain how a strut tower will move differently depending on what kind of force is loading the suspension?

The LCA moves in the exact same axis and path regardless of it's a bump in the road or compression due to corner loading, same thing with the front strut.

It's not like cornering forces the strut inwards while a bump forces it straight up, compression is ALWAYS along the arc drawn by the LCA and macpherson strut arrangement.

The only difference is how long and how far the suspension is compressed, neither of which would effect the direction the towers are deflected.

As for if strut bars do anything, notice that I said above that I would want to see measurements of tower deflection before stating a product actually does anything. Modern unibody cars are quite stiff, and I bet on stock suspension the deflection is very minimal. With stiffer suspension more loads get transferred to the chassis so it could be more dramatic then and a quality strut bar (see the size of the GC one...) would make more difference.

Another problem with this bar is the shape of it, take a bar shaped like that and push straight in and it'll bend WAY easier than a straight bar being pushed straight along it's length. It's like trying to compress an arrow along it's length vs pushing straight along the string line of a bow.
