🚨 𝑫𝒓𝒊𝒗𝒆𝒓 𝑵𝒆𝒘𝒔 🚨 Mario Clouser will drive the Rock Steady Racing #3R this weekend with the USAC AMSOIL National Sprint Cars at Lawrenceburg Speedway . Stevie Sussex, the team’s regular driver, has plans with family for the weekend, and thus, will not be in action. Sussex will be back in the ride for the remainder of the USAC season in the #3R starting with the October 16 round at Dodge City Raceway Park in Kansas. Clouser’s most recent USAC National Sprint Car start resulted in his best career series finish of 5th at Illinois’ Tri-City Speedway in September 2025. He also just wrapped up the USAC Silver Crown season fourth in the standings. He was a 13th place Fall Nationals finisher in 2019. 📸 Indy Racing Images
