I was hoping that I could run softer rates AND lower the car while not giving up on compliance. It does open a boatload / pantload /... of tuning issues, for example - what is the correct rake / ride height. What about rear CASTOR (not camber) since we can also adjust it.



Been thinking about this as well, and I need to verify this with some experimentation, BUT I guess I don't see this. I am thinking that there is NO effective difference between mounting a laser on the rim / up-right as a mirror since the mirror will also reflect all changes in x,y,z, and rotation. By compensating for rotation (easy to do if I am measuring it) I can essentially eliminate it - at least that is the theory.

I also think I understand the rotation I am seeing - since the strut is not orthogonal (in part castor) to the road surface, AND most joints have movement, when the ball joint raises, there is a vector that essentially rotates the leading edge of the rotor
