"the heims never reach there maximum angle"
Did you use a double clevis on top to keep the angle down?
Do you have any pics from the backside of the Control arms?
We have most of our parts now and Im working with them to come up with the proper geometry. I cut the lower Ball joint holder off and reset the angle and have the uppers on but I dont like the angle of the UCA alrms ther very close to max the double clevis would give me a bit less angle..
I built my own upper ball joint mount. It has a bolted on clevis and a welded on clevis. so the spread on the upper arms are wide enough to keep the heims from binding and wide enough for teh coilover to fit between the arms.
