By adjusting the angle of the LCA and the torque arm determines the instant center, right? Take the angle of the LCA and the TQ arm. Overlap them, and where they intersect determines your instant center? Draw 2 straight lines, one being the LCA and the other the tq arm, one at a slight angle, where they intersect is IC. My car squats too much right now. In essance, since my tq arm is adjustable, I can shorten it to raise the front so the mount is parallel instead of slightly forward and that would produce anti-squat. Any input would be appreciated. I think that I am understanding this the more that I read. It is a bit confusing.

Thanks

I've read the thread to the end. I was seeing if the way that I interpreted it was correct. Is my interpretation correct? I'm pretty sure that it is. Call me a retard if you want.

So which way is the correct way to find the IC with a slider on the front of the torque arm?

There are two ways listed in the thread that is linked above. One says you use a line perpendicular to front torque arm mounting point w/ the lca line. The other way says to use a line drawn from the center of the rear torque arm mounting points to the front torque arm mounting point w/ the lca line.
