Fun little track. Features everything a track should have (cameras, good AI, groove, performance), track layout is great for low powered cars and downright suicidal with 800+ hp ones (I tried :D), but that is down to Gran Turismo and its good fantasy layouts. So far I can't find any flaw in the recreation, thus it gets 5 stars from me.
Where I would go further than just recreating would be track environment, there isn't much for now, some landscape, buildings and backdrop would do great.
5 stars just because this is a great track, very nicely done, if you add to that the ability to drive the AC physic in VR on a Gran Turismo track it is fantastic. Please don't stop there, we need more Gran Turismo track modded to AC.
