While I know you are all in the heat of battle and having a blast I have a cautionary tale to tell.
All week I seemed to be struggling at the Cape Ring. I was watching fellow guys in D4 lapping over a second quicker. I could just not figure it out. I had broken in the car, was on the right tires but was doing 1:36.5xx. Little did I know my car only had 80 miles on it. Now I remember breaking it in so no idea what happened. But the moral of the story is that after breaking it in again I dipped into the 1:34.9xx's. So if you ever wondered what a 10 pp difference makes, well for me I gained 1 second a lap at the Ring in the Lexus. Your mileage may vary.
If you want to be competitive I suggest breaking the cars in
