I had my own lift off experience at MSR Cresson 3.1 you can
view here.
I normally run solo in the Intermediate group, but was able to go out with the Advanced group in the afternoon. I was significantly slower despite doing my personal best (2:34) in morning session; so I was more occupied with my mirrors and not holding up other drivers. In this segment, I stayed off-line to give pass to the Camaro who closing quickly on me. My AIM Solo data confirms I lifted ~600mS before Yaw rate detected spin. This also was the first time out running with yaw control disabled; so I clearly need some work on car control.
This raises the question of what is the best way to quickly develop car control skills. I'm thinking about going back on relative empty non-track day and grabbing a coach for half day where I can push to limit or even intentionally induce oversteer woithout impacting other drivers. They also have a skidpad, but I've never used it. Appreciate recommendations from those who have gotten over this hump.
