The drop of your center wheel should be dependent upon how rigid your frame is. We build a very rigid frame every year (welded box beam inner frame with drive "pods" bolted on each side). Last year we did 3/16" drop and it was a little too much for us, this year we went for an 1/8" drop, and guess what, it was still a little too much for our liking.
As you can see in this video: http://www.youtube.com/watch?v=OBTPLcIByU4 we have no problems turning, even with only 1/8" drop in the center wheel
