January 11, 2025 Montgomery, Alabama: Big thank you to the drivers that brought cars by the track on Sunday to measure tread width on their street stocks. The intent of the rule change was to bring the MMS Cars to a rule package that would enable them to compete at 5 Flags Speedway and Mobile international Speedway using the MMS Rule package. This has been quite a while in the making and all 3 tracks feel that this package will help to strengthen the Street Stock (Sportsman cars at 5 Flags and MIS) division in the Southeast. With this rule change we would like to announce the “Triple Crown” Tri Track Street Stock/ Sportsman Challenge. 3 races at 3 different tracks with a Champion crowned for this Mini Series.
