Im running just over 4, my limiting factor is the outer tie rod ends. When I adjust them to over 4, it starts to take camber out, so when I start to lengthen the lower control arm to get some more negative camber, I run out of threads on the outer tie rods. I need to get the longer heims he has to correct this. A question I have directly related to this, is the way TTT control arms inner pivot on the heims mount. He has a heim with spacers, which allow you to move the inner pivot point a little forward or back. The way it works, it allows the control arm to angle towards the front of the car, be square to the car, or angle back in the car, when looking straight down from above. What is the best way to set the control arm? I have mine pretty much square, but not sure if angled one way or the other would help, hurt, or not make a difference.
