My FMS C's dropped my car about 1.5" in the front and left the rear at the stock height.
The reason for them not dropping the rear is because you can buy something like the Panhard bar setup that Kenny Brown sells which has new spring perches that lower the rear about 1.5" as well. I think that's the way it works, but I'm not sure since I don't have the kit yet.
I think the B's have a little less of a drop, but I'm not positive since I have never met anyone that uses them. Anyway, a 1.5" drop isn't that much and makes the car sit the way it's supposed to IMO.
The ride isn't that bad at all with my C's and I'm even running the stiffer Koni Sports which give it a really firm ride. I'd say go with the C's and some Koni Reds. You won't be disappointed.
