Well, it seems like you know what you're doing...and if you know what you were doing, you would know how to figure that out...and if you knew how to figure that out, you wouldn't be stupid enough to screw with the springs in the first place and get yourself a real lowering kit with camber adjustments!

I seriously hope you don't get an answer to this question.
