I tend to lower the steering ratio because I like to have a more responsive GT3 when I turn my wheel while putting very little angle.
Don't hesitate to raise the steering ratio by 1-2 clicks if you are used to playing with more steering ratio.

TC: - I recommend the TC3
       - TC1 at the exit of T1 and TC1 or TC off the whole track if you master the 992

ABS: - I recommend ABS 2
         - ABS 1 if you master the 992 and his trail braking

HotLap/Qualifying lap adjustement:
- Front Target psi tyres at the end of the lap 26,9-27,0 
- Rear Target psi tyres at the end of the lap 26,9-27,0
- Rear Toe: increase near to -0,02 if you want more turning OR decrease near to 0,02 if you want more stable (it depends on the feeling of player)
- Front Antiroll Bar: increase 1 click if you want more stable OR don't touch
- Rear Antiroll Bar: increase 1 click if ou want more turning OR decrease 1 click if you want more stable OR don't touch
- Rear Ride Height: increase one click if you want more turning OR decrease 1-2 clicks if you want more stable OR don't touch

 Race adjustement (advice): I'm not telling you anything new, it wears out the rear tires a lot, so be cool at the start of the race, otherwise prepare yourself for hell at the end of the stint.
Adjust based on race duration. For 15 minutes, you can keep the qualifying setup. For endurance with a 1h/1h10 stint, opt for a slower setting for pure performance but consistent over the duration of the stint.
- Front Target psi tyres at the end of the lap 27,1-27,2
- Rear Target psi tyres at the end of the lap 27,1-27,2
- Rear Toe: increase near to -0,02 if you want more turning OR decrease near to 0,02 if you want more stable (it depends on the feeling of player)
- Front Antiroll Bar: increase 1 click if you want more stable OR don't touch
- Rear Antiroll Bar: increase 1 click if ou want more turning OR decrease 1 click if you want more stable OR don't touch
- Rear Ride Height: increase one click if you want more turning OR decrease 1-2 clicks if you want more stable OR don't touch
- Front Brake Ducts: it depends on the temperature
- Rear Brake Ducts: it depends on the temperature

My best lap with this setup: 2:15.792  (on a mega lap, there is the possibility of doing .6 mid high and if you master the 992, you can improve so much my time)

Good Luck and Have Fun.
