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 TC6.
      - TC5 at the exit of certain turn

HotLap/Qualifying lap adjustement:
- Target psi tyres 27.0-27,1
- Rear Toe: decrease one click (or more) if you want more turning OR increase one click if you want more stable

Race adjustement (advice):
- Target psi tyres between 27,2-27,3
- Rear Toe: decrease near to 0
- Front Antiroll Bar: increase one click if you want more stable and to be more safe
- Rear Antiroll Bar: decrease one click if you want more stable OR two click but understeer can appear and it will be slightly slower. She needs a slight slide to finish pivoting on the exit of turns
- Rear Ride Height: decrease one if you want more stable OR increase one if you want more turning
- Front Brake Ducts: it depends on the temperature
- Rear Brake Ducts: it depends on the temperature

My best lap with this setup: 1:42.342 (on a mega lap, there is the possibility of doing .2 high)

Good Luck and Have Fun.
