I live in Sarasota, so Sebring is my 'local track' also. I have driven it last ten years ago over the course of a few weekends with Chin Motorsports, and man! did that track eat brakes (not bad on my tires, though).
So, NingDynasty, I haven't worked with the course editor at all. Will the editor allow you to add an overpass to Turn 17, some more grandstands to 'fill-out' the area between Turn 17 and Turn 1 (adjacent to where you have correctly placed the paddock), and add some building to the area off from the hairpin to look like the Chateau Elan Hotel?
