🏁 Back-to-Back Victories! 🏁

Congratulations to Kevin Williamson and the Superior Fuel Cells team on an incredible weekend, picking up wins Friday night at Southern Oregon Speedway and following it up with another victory Saturday night at Cottage Grove Speedway!

Winning one race is tough. Winning on back-to-back nights at two different tracks takes speed, preparation, and a team that knows how to get the job done.

Proud to see an SDMF Customs chassis parked in victory lane again. Kevin continues to prove he can get it done no matter the track conditions, and the Superior Fuel Cells crew keeps bringing a fast race car to the track every week.

Two nights. Two tracks. Two trophies.

See you in victory lane again soon. 💪🏁

Another congratulations to Kevin Williamson and culp with the Superior Fuel Cells team on picking up their 2nd win of the season last Saturday at Cottage Grove Speedway.

Track was rough, elbows were up, and the competition was tough — but none of it slowed this team down. From slick conditions to hammered-out rough tracks, versatility matters, and this team continues to prove they can win no matter what the surface throws at them.

Watching Kevin stay composed and keep charging forward in those conditions says a lot about the car, driver, team, and the work they put in every week.
