Might help under heavy braking if you have front brakes. It would also help the front not to flex back only up and down. Weather that helps anything I don’t know. With two joints it could be said to be a moveable chassis component. Might need them on the rear axle with a bearing on one end lol. Gif
They both look like Heims to me… There would be very little deflection rigidity on a 12mm aluminum rod… What happens when a corner is deflected upward, the distance from that rear point is increased. That handle at the back has a set screw at the top. It looks like they can limit the amount each corner deflects with that adjustment. It’s working like the front torsion bar, but can be micro tuned…..
