Its a good start, but the turns are not accurate to real life. If you watch this YouTube video it may help you get the turns to match real life closer. The banks are not steep enough. Some turns are too easy while others too sharp. But over all you got the turn placements in the right spot. With some tweaking it could be a really good mod.

Needs to be reworked as infield section has been updated along with some improvements on the "NASCAR" turns. iRacing has a great example of a track and would hope one day for it in AC.
The sections that needs special attention (if in game "caution") is the Pit exit feeder section that extends past turns 1,2, and 3; after the "International Horseshoe", and right before entering the Main track past the "West Horseshoe".
Also for Ai to work properly the track needs to be reworked in order to map Ai. I found in mapping Ai there's 2 sections where you have to put a "camel through a needle eye" in which if the cars are off the "fast lane" they will incur a penalty.
Dearly love this track and very much enjoyed watching the 2015 Rolex 24 this past weekend! Hope to have a new one next year so we can run some cool events with it!
Been driving the oval and it's a hoot. Only problem is there's a huge bump on the track at the pit exit that launches all the road cars and you end up either in the wall or off the track in the midfield. Any chance you could smooth it out?
