Omecha

Omecha is the name of the corporation that controls the Tyson-Madigan corporation and, by extension, the TM Master Cup Series. In addition to managing the TM series' business interests, Omecha develops the MA-series spec race car chassis, available to teams in the Master Cup Series.

The chassis is normally used by Independent's Trophy teams since 2010, but they are permitted to modify it. One-off entrants for Karjala, Indy and Decatur may also run the car.

The chassis has one race victory, with Jose Luis Martinez at the 2011 Round of Daytona. It also has won the first three Independent's Trophy championships.

In 2014, Omecha introduced a new, lower-cost kit chassis, the M14. Initially created for TM Europe and TM Mexico, the M14 has also been made available to other national and regional series, most notably the National Racing Championship. An uprated version, the M17, was raced in the North American Auto Club.
