Great Job!
Some Name Corrections for Nürburgring:
GP/F and GP/D, Hatzenbects should be Hatzenb
ach or Hatzenbach-Bogen (even wrong on Wikipedia, someone should change it... looks like someone guessed the name from a bad jpg...)

Mistakes:
Aremburg -> Aremb
erg
Speigelkurve -> Sp
iegelkurve
Adenaur Forst -> Adenau
er Forst
Drei-Fach Rechts -> Dreifach-Rechts (or 3-fach-Rechts)

Pflanzgarten III -> Pflanzgarten II

Old name, not used anymore, can be deleted from map?:
Kottenborn
Unofficial names, but commonly used (should stay on map, just for information that they are unofficial):
Eiskurve, Mutkurve, Spiegelkurve, Sprunghügel, Lauda-Linksknick (not very common, i think)
As i said, i'm no expert, so others please help. Nice website about the names (in german):
