Maybe a little bit to alpha to be a v1.0 but is a good start. Don't know how is in real life the orioginal track, but if you can add in future update some background objects, like starting lights, track lights, trees (if present) vehicle services and so on it can be a good track, fun to drive.
It would be good to implement also the ext_config for CSP users, but at the moment the drop of frames is too huge to be used the RainFX function (at least on my side)
