This past weekend I mostly drove without an instructor in the car, but when I did have someone else in the car it felt more stable and settled, so the extra weight had something to do with it. I would like to have this stability without the extra weight.

Any helpful suggestion and ideas?

I would also like to understand how stiffer springs are beneficial for the track? Why do trackers increase their spring rates? I'm so used to thinking of springs in terms of a comfortable ride, I don't see the why or benefit to the spring rate increase. I know on the street they are more jarring so how does that translate to benefit at the track?
