From an engineering standpoint the weakest point of those no-name strutbars are the flanges that connect the bar to the mounting flange.

If you really want to stiffen up the chassis you would connect the strut towers using a triangulated member. In other words it would connect to the strut towers and then to one more point (3 points total). For a front strutbar I would have it connect to the firewall.



However if you are going to connect them using a single bar I would not weld the bar to the mounting flange but would use a pin or bolt that allows the bar to rotate relative to the mounting flange. If it is welded when the car flexes it will have a tendency to bend (red arrow) the bar. A thin narrow bar will not resist bending very well. On the other hand if the bar is allowed to rotate relative to the mounting flange the bar can’t be bent by the flexing of the chassis (the rotating motion won’t be transferred to the bar because the bar is free to rotate) and will instead be pushed on by the mounting flange (black arrow). The bar will do much better being compressed than being bent.



However I’m not saying that the Neuspeed bar is as bad or worse than a no-name bar only because I can’t vouch for the workmanship and sturdiness of the no-name bar and the Neuspeed looks like a very hefty piece of material.
