These will have adjustment in the camber via heim joints thus producing a different ball joint location. I remember looking at the arms on my B14 when it was on Eibachs and it looked like the balljoint needed to be moved in towards the middle of the car by an inch or two.
Basically you would thread in or out the arms to account for how low you are sitting. A set of our top mounted camber plates in conjunction and you would never have an issue.
To optimize the design we would need measurements taken to account for the rake angle of the control arm and the oem length. From this we can use trig to determine the correct lenght for a flat arm when lowered. The heim joints will be used for the slight variations in ride heights due to different springs. The heim joints will also help if you dont have camber plates installed though I would not recommend it.
