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 Nissan then has a good front end as long as its not distracted by the road. The rear end will rotate with enough pitch but lacks traction because of the immense torque, especially in low fuel situations. The electronics are a bit overwhelmed here, especially into the banked right. But the car feels nimble here and seems to like the tight track and bends. Even the kerbs (well, some) are fine to take.
The car generally feels better with fuel in the back and the quali delta isnt that large. The front bottoms less with fuel in the back. Passing should be possible with the torque, but beware of shifting too late, it costs plenty of time.

Electronics:
TC on 4 or higher for Q and potentially 3 for the Race feels best for me as the car allows you to actually work with the rear on throttle
ABS on 5 or higher seems to not lock up the tire too much.

Adjustments (you dont actually need any imo)

• The spring steps are rather large, dial in the ARBs first.
• stiffen front spring if braking into the corners is an issue, maybe start with stiffening front roll bar instead
• move BB forward if too loose into the corners.
• The weight transition needs time, don't be too aggressive, else reduce front roll bar to reduce response
• adjust rear ride height for over/understeer by 1mm steps
• Car might be faster with lower front ride height, but it will bottom out more often
• Generally the car is set up rather loose because the front has so little grip. Feel free to go back to neutral or positive toe if this is overall too unpredictable

Driving

• into turn one it will get loose, be careful on the brake and don't use too much kerb on the apex
• rotate car on throttle past the apex to pin it to the inside. Yet, don't overdo it as the TC will silently engage and stop all acceleration
• most of the time you will be able to use one gear higher than you think
• 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, there isn't much turbo lag
• 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 unload the front.
• in faster corner a tiny tap on the brake will give a good amount of extra rotation. Initiate it with the brake and maintain it with aggressive throttle

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.
