It's called geometry and an understanding of how the suspension is supposed to work.

Both the LCA inner pivot and the strut rod pivot points need to be in a line, said line defined by the LCA pin. When you use a heim jointed (get it right) strut rod you relocate that pivot by several inches. Which moves it out of line and induces a bind.

How much bind is irrelevant, it is there. how much the LCA may move is irrelevant, the bind is there.

Why would you put a part in your suspension that will induce a bind?

If you really wanted a strut rod without the bushing compliance some dislike then fab up one with a ball joint and center that joint in the line we talked about earlier. Then you get a solid, no bind connection. Probably cost less than the heim joint junk too.


Once again, I am talking about a strut rod that uses a heim joint as the front pivot point. It may or may not be adjustable, but that is irrelevant.
