Jim,
Using the coilovers and scales you can shift weight just as the Winston Cup cars do. When you change the height of the ride, you are compressing the springs which is like adding more spring rate. We have played with the changes and a friend of mine who races has a FFR Daytona Coupe and I think he wound up setting his at 53/47 for the track here. If you are going to drag race then some of the drag guys will have to chim in and help you with the weight transfers and settings as I don't know a thing about them. But the reason for the old jack bars and now the coilovers is to be able to shift weight from track to track and when trying different tires or setups. I am not good at all at explaining things and I am sure some of the others can make everything a lot clearer than I do.
