Mass finds his footing in the Late Models with Challenge Series title

By Meghan Diemel, Editor

EAST BETHEL, MN - You’ve seen him dominate the Super Stock class for years, and now he’s a threat in a WISSOTA Late Model. East Bethel, Minnesota’s Dave Mass is a rising star in the top ranks of WISSOTA Auto Racing, but it’s no surprise given the prolific career of the 50-year-old.

In 2025, Mass wheeled his way to the Structural Buildings WISSOTA Late Model Challenge Series Championship and finished fifth in national points. He won the Twin 25s first feature, as well as earned the King of Dirt Late Model title at I-94 emr Speedway. He also won the Piston Cup at Granite City Motor Park, and scored his first-ever and second Challenge Series victories this past season.

When he’s not on the race track in his No. 2, he works as a mechanic and is dad to sons Max and Brody, and husband to wife Sami.
