I just beat the FGt championship again. Won every race except the last one (skipped it).
This are the lap times, a driver IMO atleast has to be capable of, to win this event without big troubles.
I played without any driver aids except ABS1. Didn`t changed anything on the setup (well, ok, a higher top speed at fuji would have been very nice...), but I think that maxing downforce at Nürburgring and Suzuka could shave 1-2 seconds of lap time.
- Fuji, 1:16-1:18.5, pretty easy track
- Indi, 1:12-13 should be enough I think
- Monaco, well here you only have to get into P1 actually, then you can do whatever you like (except crashin out of course), no AI will be able to overtake you here, aslong as you stay on the track... If that happens, you should play Hannah Montana or something like that

I didn`t changed the setup and used the DS3, my lap times were about 1:15 to 1:16
- Nürburgring, on this track, there was a AI who was really fast. But somehow the AI always crashed at the chicane, this happened to them almost every lap. I think 1:34 to low 1:36 times should be enough to beat this without getting into problems. And yes, make sure you max out downforce before starting the race
- Monza, 1:20-1:22. If youre not good enough, you can still cut one chicane and try to block other cars
- Suzuka? No idea, its been a long time since I did this event. But I think 1:33-1:35 should be enough
(All races I started so far were dry, no Idea about rain)
