well mine is at around 3.25 inches. Wich is decent. But my center of gravity is also very good. It will sid e hill and climb steep things w/o flipping over. But i could get my chassis up to around 4 or maybe even a little higher. But you have to find the sweet spot, and i think i have. Depends on terrain, but if you are on bigger rocks, the gc wont need to be as good, but unless your are at a riverbed, or smaller rocks, i think it is necessary to have more clearance. Depends on were you drive.
