I'm j/w. im going down to Florida possibly in October to my uncles. We want to go to Sebring to check it out. IDK anything about tracks but can you show up and race your car or is it on certain days only? I think it would be fun cuz my uncles got a 06 s281e convertible mustang that we could whip around the track. I doubt I'd be able to drive it but hopefully i can at least ride shotgun.. lol
heres a pic of it. I would love to see it on the track

it was originally the base model saleen mustang and had the handling package and all the engine work of a extreme package done. Just recently he got a newer pulley and a tune since he got jealous of a roush that he liked better.. lol

only on open days and even then you may have to have a competiton license depending.. best thing to do is contact the track about open days and whos hosting them...
