I went out for mandatory group 1 my first time out and they moved me to group 3-4 for next time out. The HPDE folks said group 4 can get some madness when folks are trying to get their comp license and impress everyone. I opted for group 3 to feel it out and really have no need to push this car too hard. Passing is still a little confusing because they don't want passing under braking and in some zones...so I was probably overly cautious but whatever...still fun.
