Don't have the driving line on for a start. The only driving aid you'll need is ABS set to 1, the GT-R is very stable and has immense traction so any other driving aids will just slow you down and/or have a negative effect on the cars natural power and handling.
Go to Time Trial.
Drive around the track, but don't push the car; just drive well below your limit and get used to the track. When you complete a lap your ghost will appear. Your job now is to beat your ghost but, again, don't push it too far (there will be no need when the first time around you were driving well within yourself).
Then as you complete that lap, your ghost will be a little faster (but not monstrously so).
Each time you complete a lap, try to beat your ghost which will have been getting progressively faster. By the time you have done 10 to 15+ laps you will be starting to get very comfortable with the car and the track.
This is the only way you will get better on Nurburgring. Practice, practice, practice!
Good luck 👍
While I genereally agree with that, it all depends on your experrience with the 'Ring. For most tracks, turning off the driving line and just running the track will work the best. But considering the length and the complex nature of the track, starting a little easier would be my personal recommendation.
That's where the idea to do the AMG event comes from.
First of, you'll have to memorise the track, the general layout. While the driving line is a very safe (and, thus, slow line) around the 'Ring, that's pretty much what you're looking for.
Once can easily manage a decently fast, clean run through all of the sectors with the driving line on, running a full lap with the driving line should be the next priority.
Once that can be done cleanly, it's time to turn the driving time off.
This will help to learn the general track layout and, in my opinion, should be the very first thing to do if you want to learn the 'Ring.
From there on out, finding faster lines and braking spots is the way to go.
While the driving line may not be very fast, it's a decent tool to learn a track.
Last but not least, the car can make a lot of difference. The Nissan GT-R is, generally, very stable and quite powerful. But it's also very heavy and tennds to understerr a lot.
Personally, I'd recommend a lighter and less powerful FR or 4x4 car to learn the track. Something like the Evo IV or VI should work pretty well. The easier the car, the more you can focus on learning the track itself. This will also help to get a general understanding of the track, instead of just learning how to get one specific car around the 'Ring faster.
In general, it all depends on the experience one has with The Green Hell. In my opinion, it's better to start of easier than necessary than to make it harder than it has to be. The 'Ring is challenging enough, keeping the learning curve as smooth as possible will generally help to avoid frustration 👍
So, excuse my rant, I just wanted to give a little more in-depth advise of what i consider to be the easiest way to learn the 'Ring

So hard when you have 626 bhp at your right foot/hand. Lol, will take these tips and acknowledge that I will not get it straight away.
My point exactly

Start of with something a little slower and more managable. It'll make staying within your limits a lot easier
