I couldn't make myself pull the trigger on an arm design yesterday. The drastic sweep up to connect to the ball joint (with room for the spindle to rotate) is what bothers me.
I'm thinking that raising the car a couple of inches would greatly simplify what is required from the upper arm. I'm going to put all of the leaves in the spring and see if that raises it up past where it was supposed to sit....if not, that is a whole new problem.
I guess there is a reason most folks play "in the box".
