High Limit Racing
The High Limit Racing series, currently known as the Kubota High Limit Racing Series for sponsorship reasons, is an American touring sprint car racing series. It was founded in 2022 by five-time World of Outlaws sprint car series champion Brad Sweet and two-time and current NASCAR Cup Series champion Kyle Larson.
Overview
Brad Sweet and Kyle Larson first announced the creation of the series in July 2022. The 2023 inaugural season consisted of 12 events, which were all held mid-week. Kyle Larson was crowned the series' first champion, winning three of the 12 races scheduled.In late 2023 High Limit acquired the All Star Circuit of Champions sprint car racing series from former owner Tony Stewart. The series did not compete in 2024, but returned for 2025 with Fremont Speedway veteran Rich Farmer promoting a separate regional series.
In 2024, Larson and Sweet expanded the High Limit schedule to more than 50 race nights and increased the purse to $5 million in total prize money for the season. Sweet claimed the 2024 championship after winning 10 races.
In 2025, High Limit aired its first race on FS1, marking the first time a race was seen on national TV.
