My Front Suspension is Badly bent, What do you think?

[vwdmc16]

so the problem with a theoric lower wishbone is that the sway bar becomes too stiff (because it is born from factory to do the anti roll job and the triangulation job together)
what about , in the lower wishbone scenario, to change the entire sway bar with a modern type one and to route it over the crumple tubes?

The bar doesnt become too stiff, its just that it has to force LCA forward and backwards as the bar travels through an arc. This arc doesnt move the arm a huge amount since the bar is only rotating a few degrees however even the relatively soft rubber bushings between everything can absorb only so much, then the conflicting members start to bind. A true and sturdy triangulated wishbone wants to travel up and down only but the end of the sway bar wants to go in an arc, so you must connect the two with a double jointed link that will convert the motion from one part to the other.

Swaybar is perfectly capable of deforming itself in lieu of rearward LCA movement. It's a very bendy piece of metal (that's why it is so unsuitable as thrust arms). Swaybar also makes two 45 degree bends between the LCA's and its crumple extension mounts -- introduces even more flexibility (versus two 90 degree bends):

Mike Loasby experimented with lower wishbones at the factory, which have virtually no provision for fore/aft movement. Those same experimental wishbones have been on Rob Grady's car since at least the early 2000's no problem.

Swaybar locking up is a Red Herring.

Gee, if only there was a part that could do that.
