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 TC1

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
- Front Toe: increase 2-4 clicks if you want more turning OR decrease 1-6 clicks if you want more stable (it depends on the feeling of player)
- Rear Toe: increase max 4 clicks if you want more turning and no decrease
- Front Antiroll Bar: decrease 1 click if you want more turning
- Rear Ride Height: increase one click if you want more turning OR decrease one click if you want more stable

 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.
- 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
- Front Toe: decrease 1-6 clicks if you want more stable (it depends on the feeling of player)
- Rear Toe: don't touch
- Front Antiroll Bar: decrease 1 click if you want more turning OR don't touch
- Rear Ride Height: increase one click if you want more turning OR decrease one click if you want more stable
- Front Brake Ducts: it depends on the temperature
- Rear Brake Ducts: it depends on the temperature

My best lap with this setup: 1:57.545  on a mega lap, there is the possibility of doing .4 mid low and if you master the 992, you can improve so much my time

Good Luck and Have Fun.
