There are 2 Laps in this package with the same setup.
The faster lap is me pushing like the pros would drive a normal lap, using all the track, braking & accelerating aggressively, exploiting the car's strengths and weaknesses.
The slower lap is dialed back a bit, not using all the track, not braking at the very limit, giving the car more time and accelerating with more ease.

As you can see, both times are easily faster than the average laptime you need to achieve. Maybe the more "leaned back" approach is actually more insightful than the attack lap.

Electronics:
TC3 should be a good fit for most people - it still accelerates. TC 4 or 5 if you like it more stable.

Adjustments (you dont actually need any imo)

• reduce front bump stop range if braking into corners is an issue, or stiffen front spring.
• move BB forward if too loose into the corners, more rear bs range (do on click at a time max, it will affect eau rouge)
• more positive rear toe if the car is dancing on the brakes just too much

Driving

• Basically all turns need careful trailing, but you can still push the higher speed corners for some reason and pitch the front into the ground into the longer corners, the rear will stay controllable
• aim for late apexes, try to trail deep, immediate throttle [+management once the turbo spools up], little to no coasting. The differential will pull you back to the inside, hopefully
• shift at 153, 185, 220, 252
• The break is your friend here: The brake controls the speed, the pitch and how much weight you move forward. You will have a noticable impact on rotation with small brake inputs and while letting go off the brake during turn in. This is per design to keep at least some weight on the rear axle and not run max rake. Use the brake to pitch and force the car into the corner, it really generates a bit of front end grip. Check the data to see what I mean.

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