Oh man, oh man...where do I start?
First of all, it is not a good idea to change your setup last-minute, and not test it thoroughly first.
I also need more practice time throughout the week.
Secondly, I put waaaayyyy too much fuel in my Ferrari. Twice as much as I needed. So the car drove like a tank as a result. That bit of extra weight probably caused my brakes to overheat and upon further inspection, that setup I dug up last-minute had its braking pressure maxed out and its brake ducts set to 1. So basically my brake discs were tortured all race long, which caused them to reach temperatures of 1000°C+ so about 5 laps before the end they were burnt too a crisp. Charcoal brakes.
So I learned a lot again, last night. This game loves to school me hard.
