The AC/DC man was back behind the wheel in Florida
Johnson was racing for the 50+Predator/Alegra racing team at the endurance race over the weekend.
He and his team finished a respectable 32nd in the race.
Ahead of the race Johnson had told ESPN "It's a funny old world. It's a yin-yang world where all the sportsmen I meet want to be rock 'n' roll singers, or in a rock 'n' roll band, and all the musicians I know they want to drive cars. But there is something about driving a piece of machinery that is very quick and beyond your ability ... What you're doing is you're always checking the level of your cojones, if you know what I mean. It's one of those things where you scare yourself half to death. So the next time you do it you're not nearly as scared. You just get more and more used to the speed."
