General:
Race drivers always seek for the duality of physics: He/she wants traction. And Rotation. A good front end and a good rear. The truth is: It's all always there, but what the driver is unhappy with is laptime and corner speed. Always. The Ferrari has one of the best downforce you can find and it has good electronics, too. But it's incredibly stiff  and resopnsive in general which makes it a victim on bumpy circuits. It has insane speed in fast corners and will suffer a bit from low speed acceleration that offsets its top speed and downforce. It does not like rake however benefits from it aero wise.

Electronics:
TC1 on 3 or 5 for Q and for the Race feels best for me as the car allows you to actually work with the rear on throttle. I would keep TC2 low or off.
ABS on 5 seems predictable

Adjustments (you dont actually need any imo)

• The spring steps are not linear, only a few rear and front pairings will actually make sense
• stiffen front spring if braking into the corners is an issue or the car is generally too oversteery for you.
• reducing negative toe or going positive on the rear can help this further, but the speed certainly is fastest with negative toe.
• move BB forward if too loose into the corners. 
• adjust rear ride height for over/understeer by 1mm steps.
• experiment rather with roll bars for balance instead of touching the aero platform
• For lower rear tire temp you will have to shift the balance further or increase rear ducts. Lower rear ride height, higher front, stiffer front spring, etc. 

Driving

• into the corners you can be quite aggressive with the brake, the ABS will sort you out. 
• Onto the throttle don't just floor it in the slower corners, give the car some time (say, half a second) and it will thank you
• aim for late apex in hairpins, try to trail deep, immediate but progressive throttle, little to no coasting in tight corners, aggressive throttle in longer corners. early power is very crucial to work the diff and and keep the rear rotating to overcome the aero shift.
• In the chicanes be gentle with the weight transfer (your front end is better than the rear and will build grip too fast!) and try to live with minimal corrections on throttle and brake to stay on line.
• Use small throttle and brake inputs mainly to keep the car rotating, during coasting the car will understeer
• track limits tend to be wide, use it.
• the car does rarely run into the limiter when bouncing over the grass, so dont be too afraid of running wide in t3.
• even in the lower gears you need to go near the rev limiter, as thats where the power is
• in high downforce corners the car has great yaw tolerance (being sideways and not losing downforce) and you can just use the throttle a bit to stabilize almost like the Porsche

LFM:
Just reduce fuel load to 45/49L. Balance should become even more neutral. Adjust rear ride height +-1mm to your liking. Most likely up by 1mm for medium fuel loads.
