These are interesting. Full disclosure: I did work on development of them a while back.
They have been validated and I guess now being brought to market. This is something I will be picking up - need to service the driveshaft first probably and a few other things as they arent cheap.
Long story short is they correct roll center for lowered vehicles (on coilovers or the like for track duty and such). They eliminate bump steer and have perfect ackerman.
Just sharing the options out there as something that will be part of this build at some point. Id like to do a whole car study, reverse engineering the whole suspension instead of just the front end.
