I totally disagree.
Yes, the suspension loads are transmitted through the torsion bars, and the shock towers are technically only there to support the shocks.
But you're not just bracing the shock towers. You're adding an entire path of bending resistance to the entire front half of the car. The shock towers are welded to the frame rails, bracing them off of the fire wall triangulates the whole front half of the frame, which supports the K member. These are all unibodies, the front frame rails are only held onto the body by some spot welds. Frame connectors do wonders to reinforce that, but you still only have reinforcements in 2 planes. Adding the shock tower braces adds a vertical component to that reinforcement.
I think frame connectors should be added to every single one of these cars if you're going to bother to do any amount of repair or restoration. The shock tower braces and radiator support reinforcements don't have as big of an impact as the frame connectors, but to say they do nothing is just untrue. Not every driver will notice the benefits, but that doesn't mean they aren't beneficial. I went a step further with my Duster, adding "J" bars that run from the firewall to the frame rails above my tubular radiator support, and also brace the tops of the shock towers. The difference in body flex between my Duster and my cars without those reinforcements is very noticeable.
