In the 360 Sprint Car headliner, outside front row starter Tony Wondra of Campbellsport jumped into the lead on the drop of the green flag before Adam Miller of Plymouth flipped in turn four on the opening lap to bring out a red flag.
Following a complete restart, Wondra again grabbed the lead while two-time PDTR 360 Sprint Car champion Kurt Davis of South Milwaukee, who started third, moved into second with the fifth-starting Arenz bolting into third on the opening circuit.
While Wondra led, Arenz moved in to challenge the high-riding Davis along the low line on lap 4. On lap 5, Tyler Davis of South Milwaukee and Anthony Knierim of Franksville collided in turn two to bring out a caution.
On the restart, Jack Vanderboom of Dousman and Doug Wondra of Campbellsport got together in turn three, which sent Vanderboom flipping on lap 5.
Davis pulled off an impressive low move in turn four on lap 6 to wrestle the lead away from Wondra. Meanwhile, 2017 PDTR 360 Sprint Car champion Brandon McMullen of Oshkosh was using the high groove to vault into second from his sixth starting spot on lap 7.
McMullen continued to ride the high groove of the lightning fast track surface to pressure Davis for the top spot. On lap 9, McMullen surged ahead of Davis along the outside groove. McMullen maintained a solid cushion as the leaders encountered slower traffic on lap 13.
Two laps later, Arenz moved into second before Tyler Tischendorf of Waupaca spun in turn two on lap 16. On the restart, Arenz ducked underneath McMullen to assume the top spot on lap 17 exiting turn one.
After that, Arenz moved up to the high line and pulled away from McMullen, who worked both the bottom and top of the track in an attempt to reel in the leader over the next nine laps.
Just as the leaders were about to catch the back of the field, the checkered flag flew with Arenz claiming his third career PDTR 360 Sprint Car A main victory and ninth overall Midwest Sprint Car Association main event triumph.
McMullen wound up second, Davis was third, 2008 PDTR 360 Sprint Car champion Lance Fassbender of Burnett took fourth after starting eighth and 2011 PDTR 360 Sprint Car champion Ben Schmidt of Howards Grove charged up from his 16th starting spot to take fifth.
