“I’m super excited to be back in SRO full time after a hiatus in 2023. I’m looking forward to joining Justin, who is a great young talent who’s had success in his career already. I’ll do my best to teach him what he doesn’t know and to mentor him into these more advanced races with pit stops and driver changes. We’ve already tested for a day, and he’s shown that he is naturally talented. He’ll have a great group around him to get him up to speed, and I’m looking forward to it.”  -Robby Foley
