Mittler with his MB Motorsports team made over 300 starts as a team owner in the NASCAR Truck Series and was a part of the series since its inception in 1995.

Mittler helped many racers get their start in the national series including Carl Edwards, Brad Keselowski, Jamie McMurray and Regan Smith.

The veteran team owner almost scored a win in the dirt race at Eldora with dirt-track hot shoe Bobby Pierce, who won two straight pole positions at Eldora Speedway and finished second driving Mittler’s No. 63 in the race in 2015.

Mittler, who made it known last fall he was fighting cancer, was 67.

Chris Blair, Executive Vice President and General Manager of World Wide Technology Raceway in Madison, Illinois, on the passing of Mittler.

“Our entire team, and families, are saddened by the loss of Mike. He was a great friend and loyal supporter of our track,” said Blair. “I had known Mike a long time before my move to St. Louis and he welcomed me and treated me like family upon my move.

“In addition to my work at the track, Mike had been a supporter of my family race team. He provided shocks to my son, Austin, when he was an eight-year-old Quarter Midget racer. When Austin was preparing for his first Super Late Model race, Mike was there at the track coaching him.

“Mike was special. He was a great man who inspired many. I value each moment shared with him through the years, especially those in the garage along with my son.”

Brad Keselowski, whose family was close with Mittler, also expressed his sadness with the news of his passing.
