Well, that didn't do much. Quickly made some measurements and there was a half inch difference between the radius arms at the point the sensor bolts to them. Fabricated a new bracket with the mounting holes 1/2 inch further apart, bolted it on, fired her up and it made absolutely no difference at all other than caused both sides to raise a little. Just sat there wonky. Pressed the button to raise the suspension, both sides went up by the same amount and sat 2 inches higher.....but wonky. Hmmmmm, I also noticed that at one point while I was fiddling the arm for the sensor dropped down when I unbolted it causing the car to come up with an SLS error light on the dash and commenced lowering itself to the bump stops. When it did this the extended bracket I'd made would cause the arm on the sensor to bend and eventually snap. So doesn't look like it's an avenue worth pursuing! Old one was reinstalled and engine restarted and she's back to how she was this morning with the Terrafirma +2" bracket on. Shall have to see how much the calibration is this afternoon
