Hi guys
I currently have Tein S Tech springs on my G37xs coupe, the rear camber got really negative after the drop so I purchased Eibach rear camber arm trying to fix it and try to get the camber close to the 0. After I done the alignment with the Eibach rear camber arm I noticed there is still about -1.7 degree on the rear, and the bolt on the camber arm are adjusted to the left (red circle on the pic) or towards outside of the car. I'm really confusing because this camber arm says +/- 4.0 degree, it should be easy to handle 1.9'' drop at the rear.

 

Did you get a toe bolt kit to go along w/ the arms? If not, your original toe bolt will be maxed out to keep that critical point in spec and you will have to run more camber. If you get the toe bolt kit and elongate the bolt slot, you should have no problem w/ a much wider range of adjustment.
