Won the RBR race today on hard difficulty in the C9 along with the CRB. As with the Fuji race before, I tried to go for a dry race.
I think this race was the hardest of the 3 for me, mainly because the top AI cars have really good pace, and some of them could run the entire race without pitting. What made it even worse was that I had to use fuel map 4 and short shift throughout the race to save fuel in order not to pit, so that made it very difficult to pass the top AI cars on the straights. It was also more likely to rain than the Fuji race.
However, I did manage to find online very nice suspension and differential settings for the C9, and they turned out to be very good at RBR (details in my YT video/description). I of course had to tweak the aero and the ballast to meet the PP requirement, but I was able to run on RH tires with full power.
As for the race itself, it threatened to rain in the latter part of the race, but luckily the rain stayed away from the track in the end. I was able to hunt down all the top AI cars except Grady in the XJR-9, but luckily he pitted at the end of lap 9, and after having to do fuel saving for pretty much the whole race, I used my nitro power on the last lap to snatch the fastest lap from Grady to cap off the race 😊
