The Casper Speedway features local classes as well as regional sanctioned racing classes from Wissota, I.M.C.A., C.L.M.A., etc… Local class rules are posted below, as well as links to the regional class rules. All racers are expected to understand and follow their class rules regardless of what group they are representing. On occasion, a special event may be added to the race schedule and any specific rule requirements for that event will also be posted here.
