Best lap from the final OnGrid event on Sept. 6 -- after a differential failure on Saturday morning, I had to swap in a stock Torsen differential (no more Giken) and send it in suboptimal conditions on my 2nd session with the new to me diff. Start of session was actively raining and was 10+ seconds off pace but dried out *enough* for a decent hail mary lap.
