GREEN BAY, Wis. (May 13, 2026) – The TUNDRA Super Late Model Series begins its 16^th season Saturday at Wisconsin International Raceway with the Spring Classic 75.

The field is littered with past series winners, former Champions, and contenders.

The past three Spring Classic winners will be looking to get off to a hot start to the 2026 season once again. 

Grant Griesbach won last year’s TUNDRA stop and went on to win the Fox River Racing Club Championship as well as the Red, White and Blue, and Slinger Speedway titles. Ty Fredrickson won the 2024 running, then went on to win the TUNDRA and Kulwicki Driver Development Championships. Sawyer Effertz was victorious in 2023, then went on to win the FRRC and RW&B titles.

Plenty of other contenders are in the field – including Dalton Zehr, who is looking to get the monkey off his back in TUNDRA races at WIR. Zehr won in 2014 and has come close several times to winning again including last year.

Young drivers to watch will be Kulwicki Development Program racer Penn Sauter and Cody Vanderloop who threatened to steal the win from Griesbach on the final lap of last year’s TUNDRA event at the half mile.  2025 KDDP finalist Noah Eisenhower will also make his series debut.

Others with strong backgrounds at WIR include multi-time former Champ Jeff Van Oudenhoven, former track champs Andy Monday and Bobby Kendall, and TUNDRA standouts Jeremy Lepak and Brock Heinrich.

TUNDRA will be joined by the Pro Late Models for the Alburetor 28 honoring the late Al Golueke and the Mid-Am Racing Series for the Vercauteren Memorial 30 honoring series founder Gary Vercauteren and his family.  Qualifying begins at 12:30 with racing at 2pm.
