The Bob Hilbert Sportswear Short Track Super Series (STSS) Fueled By Sunoco is a touring series for the big-block/small-block Modifieds featuring many of the sport’s most talented drivers. The STSS offers a mix of full-time drivers and weekend warriors battling for lucrative purse structures and series point funds.
The STSS has North and South Regions for its Modified division with $15,000 championships ($46,000-plus total point funds for each) available.
Joining the big-block/small-block Modifieds, the STSS presents a touring series for the Crate 602 Sportsman division as well.
The STSS manages the American Racer Cup, a home-track program rewarding drivers for competing regularly at home tracks utilizing American Racer tires.
The series was formed by special-events promoter Brett Deyo late in 2013 and the series has grown significantly since its inception, entering its 13th season in 2026.
