(June 27) – Passing seven cars and taking the quick lead wasn’t even the most challenging part of Matt Olson’s run to the IMCA Sunoco Stock Car checkers Saturday at Arlington Raceway. Tenth starting Zach Davis caught Matt Looft in the final turn for the Karl Kustoms Northern SportMod victory and Bill Johnson led the last five circuits in a caution-free IMCA RaceSaver Sprint Car contest. Brandon Beckendorf also started 10th, and won the IMCA Modified main event. Dan Mackenthun led start to finish in the IMCA Sunoco Stock Car main and Nate Coopman took the Mach-1 Sport Compact checkers. Probst ended in second while Luke Trebelhorn got around his brother Jed to take third.
