The design of the particular component looks way too flimsy in bending and torsion to offer any stiffness improvement to an already stiff chassis.
Hi swamp2,

Not trying to start an opinion war or anything, but this topic has been discussed for years...remember Neuspeed? They made a solid construction strut brace for the GTI crowd with this claim. Tests were done, and the benefits over a pivoting or multi-piece strut brace could not be concluded.

The fact is that you do feel a difference it the roll and flatness of the car after installing the rear strut brace. Not like you "feel" horsepower gains. It ties the body together between the upper end of the strut towers. This fact alone makes the body stiffer. Now can a solid bar make it stiffer? How much stiffer? Will a triangle bar welded between both struts and the rear of the truck be even stiffer? At the end of the day, with this bar you have an easy disconnect feature which is not available with the solid bar design. No need to remove all of your interior as in the picture above. Some of us still need our trunk sometimes. IMO this is the perfect solution for a rear strut brace.

Again, just giving the benefit of why ACS made the bar this way.
