i did not know that, what series runs there
No NASCAR yet, the 12 Hours of Sebring is still the main venue. However the track does have a few vintage events and many days of corporate testing. Local 1/8 mile drag returned last year. Some think NASCAR leased the track to keep out the competition. Never ran it myself, but know a few who have. They say it gets your attention real quick, or you get a good seat to watch the rest of the race.
