When you use springs to lower the front, you lower the roll center much further than the center of gravity (the control arms become angled).
Also, the springs are located in-board, so despite the use of heavy springs, the wheel rate isn't very high at all. You want the weight:wheel_rate ratio of the front & rear to be about the same, so you don't get the for-aft rocking/sea-sickness.
With a 60:40 weight distribution, 200# springs in the rear (stock location) should have about 600# in the front (stock location).
The factory balance isn't right, and some of the 10% stiffer kit's aren't either...
