Seat lowering

Hi all, I’m new to this subreddit but i’ve got a question for anyone who may have an answer. I’m in the market for a c7, and found a 7mt stingray that i’m strongly considering buying. Problem being that i’m 6’3, and my head touches the back roll bar support when the seat is fully back and lowering the seat all the way down doesn’t help much unless i move the seat up a little then it’s somewhat better. Is there anyone who knows if there’s a kit to install, or some way to make the seat just a little bit lower so i can fit with the seat all the way back?
