Automatic/Manual, with or w/o AC

I installed the FMS B springs about a year ago. The front sits WAY too low for my tastes. I have decided to put some stock ride height replacement coil springs in the front and keep the B springs in the rear. My question is that when I look on the websites (autozone, advance...) the springs are different for the transmission and for the AC. I am guessing that this has to do with the weight of the front end of the car. My car being an automatic (with dreams of converting to a 5 speed someday ) with factory air conditioning, if I put in the springs for a manual w/o ac would this drop the ride height from when it was stock? Or is there just not that much difference in the springs and I wouldn't be able to tell?

I didn't think that there would be much of a difference, if any. That being said, there are different part numbers for the different transmission, ac, and bodystyle (coupe, hatch, convertable) combinations.
