Oil temps were pretty consistent at 5 bars, but hit 6 bars for a few seconds on the last session. I'm pretty sure that that is the ISF's weakest link. It was approx 85 degrees for the last 2 sessions.

Now I know I have a fair amount of mods, but I still eagerly accepted the instructor's praise. He is a 20 year racing veteran who currently races a 2010 (?) M3. He was amazed at the ISF's speed and grip. He said the balance was way better than his M3...though I'm pretty sure that is mostly because of the tires, diff and coilovers.
