Late Models: Sunday of the Iron Cup we will be racing Late Models under Tri-State Rules instead of IMCA. With the Tiny Lund being next weekend for IMCA Late Models, it makes sense for the racetrack and racers. In addition, the Tri-State Late Models Series will be in attendance on Friday and Saturday. The two highest IMCA Late Model finishers will receive $100 on Sunday. We hope to see you next weekend at the Iron Cup!

We will be opening up the SportMod division next week to allow USRA B-Mods and Wissota Midwest Modifieds to compete with no spoiler next weekend at the Iron Cup. Each type of mod must follow their own rules. All other classes will remain IMCA sanctioned and points. There was interest to participate and with the recent schedule changes yesterday we will allow that for the Iron Cup. Thank you.
