Do your homework on the lowering options. I had H&R springs on a car years ago and removed them. The front was too low and the rear wasn't low enough, and there was no way to raise the front. What is the distance in inches from bottom of fender lip to wheel center, front & rear? Note the fuel load also, this affects the rear measurement.
Your ride height looks nearly perfect to my eyes. If you want the rear lower, try Limited springs first, or cut 1/4 coil off the existing rear springs along with an SLS adjustment. I assume you are on 1-pt front pads already, if not, try that up front.
