Track is fun but I've noticed a couple of issues when racing here:
1. The blue tyre wall on the exit of T1 has no collisions and the car can just go straight through it.
2. There seems to be no track limits at all on the concrete between T15 & 16, I can understand on the outside of 16 as cars always run wide there, but you can pretty much just straight line T15 it seems into 16 and get away with it.
3. Sometimes the tyre seems to clip through the T1 exit kerb which can cause spins once the tyre gets pushed up ontop of it, this seems to be pretty minor though but I thought it was worth mentioning as it's what lead to me discovering point #1.
I can provide proof of all 3 of these points if required, as they coincidentally all happened in the same race but #1 & #2 can be easily replicated. Sebring's an awesome track though so it's great to have a working version for AC.
