Exactly so. This is drag race only gear IMO, there's almost no chance at all this system has decent Ackerman for the street. The support of the upper coil over mount is also insufficient for the weight it carries for long term street use. For example, it has about half the strength of the HDK upper shock mount hoops just based on its mounting to the frame.
The design of the K makes it pretty lightweight use also. The entire strength of the K frame in torsion and other modes of loading boils down to only the strength of this section of tube, which has a really small cross sectional area regardless of its wall thickness.
