stock setup way too quick?

[SwearImSober 0]

In the manor around Baku i use low downforce adjust the camber so it's much quicker but tyres degrade much quicker a long with a few other small changes and I do about a high 1:45 minute lap. I then use the stock setup and set a 1:45.5 lap time and it was only 1 lap, I made so many mistakes on that lap I could easily improve by a second or two

Anyone else feel this way? BTW ai isn't aggressive enough on legend ai


Edit: I just finished qualifying on legend difficulty and came 12th with a lap time of 1:43.874 with the stock setup
