Electronics:
TC1 on 3 and TC2 on 4 feels best for me as the car allows you to actually work with the rear on throttle - very rare in this game and simply nice to drive.

Adjustments (you dont actually need any imo)

• reduce front bump stop range if braking after the straight is an issue, or stiffen front spring.
• move BB forward if too loose into the corners, more front ARB could also help here
• The car most likely still takes more rake if you can handle it
• race setup might be able to run more toe still

Driving

• Basically all turns need careful trailing, but you can still push the higher speed corners - the car tolerates a lot of yaw
• its very important to slam onto the throttle in all the fast bends right after trailing in first and last sector
• rotate car with hard throttle to keep it rotating - might need stiffer rear spring still
• bumps in the chicane are tough on the car, can't use the entire kerb
• aim for late apex in hairpins, try to trail deep, immediate throttle [management], no coasting.
• the inside kerbs in the last 2 corners help rotate if you hit them just slightly 
• shifting at 7000-7100 rpm, don't max out revs

LFM:
Just reduce fuel load to 45/49L. Balance should become even more neutral. Adjust rear ride height in +-1mm to your liking (higher for oversteer, lower for more neutral behavior).

Setups

• The 42.9 is done with the lower wing Q setup - this is rather loose, but ultimately faster
• the 43.1 is done with the much more stable setup
• race setup is based on the stable version
