First session with some new Jongbloed 11in front and 12in rear wheels. Same Toyo RR 315/30 tires from last season. Corded the left front after just 1 session each by me and my son. Next year we'll come back with some fresh tires. 
Lost about .7 sec from missing my braking point at Turn 3 and passing a Cayman that narrowed my track out in Turn 9.
I can take Turn 1 at least 5 MPH faster and carry that speed into Turn 2.
Using the Garmin Catalyst for the first time. I love it.
