You're on a roll Juan. You might consider including in your overview which version of a track you're improving. Guys have many versions of Spa. Sure like your plan though.
At first I thought...what...Spa already has spectators, then I tried the track first at default then with your mod and...MUCH BETTER! Great mod..thanks!
It is the version of Kunos, with the skin of Daniel Paez and the extension of Pyyer.
I added the links in the description of the video.
