Thunderhill West - BMW Z4 -  

It was very hot. Spiked to about 102F again... Starting at 117C coolant temp the engine will pull timing. I had to do cooldown laps in the later sessions.

@maxpp Oof. That sounds awful. I find West is the hardest on our Z4's cooling system for sure. Brakes and tires held up well?

@@rsipad Both worked fine given the conditions. The tires have a bunch of heat-cycles in them now and it shows.
