I don't like either of those tracks and it will take about 3 years worth of attempts before you get a fast clean lap around the nordschleife.
GT5 was my first motorsport sim game in a very long time, and I never even looked at or knew really, what the Nurburgring even was. I was so ignorant, but I knew I was hooked on this game, and vowed to learn it. I knew the NFS series was dead in the water, so GT is all I had to look fwd to, and so glad I invested time in it. (hobby)
I didn't touch online until I forced myself (with good motivation coupled with adrenaline and stress) to get at least all silvers on the AMG academy special, in game.
As soon as I saw even the remote chance that I was actually getting golds in certain sections, I said to myself, all gold it will be.
Since about 10 months now, 2 hours a day on the Nur is all I do.
This will be my first TT where I can (hope) show my name in the top 1,000 , and I'll be thrilled with that.
Knowing the track, is 85 % of the battle, you can then take any of your 1,300 PD cars in your garage, and enjoy it, aid free. ABS is optional, but not all that necessary.
now which car to do... I'm so used to 500pp street, but I did learn the track in the F1 and FGT lol.
