I have been racing the Puma 052, which is really fun to drive, against the AI. Short 15 min races, AI at 90. I am pushing to stay in the mix, but after a few laps ( at Lime Rock, which is hard on the left side), my tires are starting to cook and I have to slow down or begin to loose grip. The AI just keeps hammering and I may as well pit and go for coffee. Any setup tips or is the AI just invincible?
