The last question I seem to have is what is the downside to using the up-stops? I have never really used them in any car, and it seems that the general wisdom is to not use them, just can't make out why.
The droop or amount of up travel is used to balance the shift of weight transfer front and rear under acceleration and deceleration. It's also used in conjunction with your preload of spring to keep your wheels on the road when turning and rolling and when on a bumpy track.
Keeping your left to right uptravel symmetrical is important, and the amount of uptravel is directly relative to the amount of spring travel as its not the shock rebound.
Consider if you use your springs to reset ride height you are changing these parameters as well, in nitro on road racing, tyres wear down and geometry changes on the fly.
