The 21st edition of the Superkarts! USA ProKart Challenge is projected to be one of the best seasons in the last decade. The organization’s flagship regional program is set to contest six rounds of racing over the course of five weekends, featuring three premier facilities in the southwest region of the United States.

Radford Racing School and Formula 4 United States Championship (F4 U.S.) will once again host the Radford Racing School F4 U.S. “Karts to Cars” Scholarship School, a joint venture that brings together some of the best karters from around North America to get their first experience in a single-seater racecar.

The association will continue this synergy for the 2025 season with the first three months of the year featuring back-to-back events.
