Use upper arm length for camber curve you want at that wheel. Mount upper control arm mount so that it is inline with lower control arm mount from a side view. use software or draw out on paper for the roll center you are looking for.set upper mount at these positions and weld her up. i have done this with stock mounts many times and you can not even tell anything has been changed. makes the car much more consistent!
