Notable opportunities are... - Brake harder and longer into 1 to get on gas earlier up the hill
- Shifting halfway up the esses is worth about 2 tenths
- A shallower entry into the bus stop helps carry more speed through the bus stop
- Turn in earlier for 5 (mislabeled as 6 in the video)
- Brake later for 6, leave in 4th to mitigate oil starvation
- Brake later and harder for 7

Ducting might be an issue here.
I track my 2011 328 xDrive at High Plains Raceway in Colorado. High altitude is a cooling nightmare. The track sits at 5,000ft and without an oil cooler, hitting 300f in summer takes 2-3 laps.
I installed a set up from N54/55. Nothing else. Regular thermostat, regular oil cooler. I have never gone over 260 in the summer at 101-102f at that altitude. At that altitude, it is harder to cool off the engine at 60 degrees than in the middle of the summer in Miami.
My setup, on the other hand, has that duct that comes on the E90, which splits between the duct for brakes and the duct for the oil cooler.
Also, I run heat during tracking, full heat and maximum fan strength. Also, coolant is only 10% concetrated for better heat dissipation.
