USA regional program for a third time since opening its doors in August 2024. Rounds One and Two of the 2025 championship program kicked off with perfect racing weather to begin the 21st season of the series.
The sold-out Formula Works KA100 Senior class welcomed 52 drivers around the 1-mile circuit. They were led by veterans Jake Drew and Oliver Calvo in the opening qualifying session on Saturday, with the two separated by only 30 thousandths. It was Drew’s 1:02.994 lap that was best in the session. Drew and Calvo were shuffled back at the start of the Prefinal, allowing Jackson Menchu to show the way. He would get overtaken by former SuperNationals winner Zachary Claman Demelo and Shea Aldrich to finish 1-2 at the end of the Prefinal and lead the field to the green flag for the Final. The two exchanged the top spot several times over the first half of the race until 2024 series champion Keagan Kaminski worked his way up into the battle. He grabbed the lead on lap 10. Kaminski continued leading over Claman Demelo and Calvo until the two challengers were involved in an incident. Claman Demelo retired while Calvo fell outside the top 10. Senior rookie Johnie Stamps became the new challenger for Kaminski as they fought to the checkered flag. At the line, it was Kaminski taking the victory ahead of Stamps and Menchu. Josh Campbell was fourth with Theo Kekati in fifth.
