4 Link setup

[454SSguy]

So I've been reading quite a bit about how a 4 link setup for drag and a 4 link setup for auto cross are different. The biggest issue I hear about is a drag 4 link will bind when used for autocross. I don't get this since most heim joints will articulate 18* and some up to 24*. I assume then it must be in the design of the 4 link itself. So how would you setup a 4 link to not bind? Triangulate 4 link? I plan on doing a simple 4 link and watts link when I get home, this is why I'm asking.
