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 or 2, it's a really good compromise

HotLap/Qualifying lap adjustement:
- Target psi tyres 26.9-27,1

Race adjustement (advice):
- Target psi tyres between 27,0-27,2
- Front Toe: decrease near -0,40 > -0,34 or -0,30
- Rear Ride Height: 59 > 58
- Rear Brake Ducts: 3 > 4 (it depends on the temperature)

Good Luck and Have Fun.
