I was able to get a 30 lap race at Michigan. I qualified 2nd 30 cars approx. I used you first setup you posted. I finished 2nd over 4 sec behind. I thought If I took an easy I would be able to catch the leader but the joke was on me. Car seemed pretty good. I don't know I am going to now try your loosy goosy one but I think you are right though. Even with your first one there was a couple of times where I felt the rear just twitch with a car behind me. I will try it anyway though.
