Alright,
After listening to everyone, and talking to Joe from PDA on the phone, I've made up my mind.
I'll be there next Saturday. Joe convinced me that the road course is much different than autox. In autox, I'm turning left/right/left constantly and throwing the weight around. The 4 link just can't keep up. The sweeping turns on a road course will be much different. I'm just going to drive at a pace that's comfortable for me.
So, thanks for everyones patience with me, and sorry for my indecisiveness. I'm very much looking forward to the track time.
Steve
