Ronnie Johncox. Ronnie Johncox was an Indy Car owner and driver who was participating on the Indy Car Series at the time of purchase. Johncox operated and promoted the track for two seasons until he closed the track after the 2000 season due to financial issues. The track remained closed for the 2001, '02 and '03 race seasons. In 2003, the track was purchased by Spartan Speedway owners Paul Zimmerman and Jim Leasure, and the track re-opened for the 2004 season as "Calhoun County Speedway". In 2005, the track started the season as Calhoun County Speedway. During the season the name of the facility was changed to Springport Mid-Michigan Speedway. In 2006 the track was promoted by local racing legend Gary Fedewa (along with Spartan Speedway) but again, financial issues closed the track early, in August. In 2007 Zimmerman/Leasure leased the track to local racer and businessmen Maurice Randall. Randall was formerly a NASCAR and ARCA driver. Track successfully completed the season, but for 2008, track ownership decided not to lease the track out and instead operate it themselves. The 2008 season was completed in full and at the conclusion of the season the track was sold/leased to Jerry Rabbers. Rabbers changed the name of the track to "Mid-Michigan Speedway" and launched an ambitious schedule and payout. In July 2009, the track suspended operations and in August ownership/operation reverted to Leasure. In 2010 and 2011 the track was successfully leased and operated by Steve Martin. The Springport Mid-Michigan Speedway website http://www.springportracing.com is full of information for the current season. If you have been to the track and watched, or raced, come back and enjoy yourself again. If you have never been, there could not be a better time to give the premier racing facility in the tri-state area a try. Springport Mid-Michigan Speedway: Michigan's Ideal Speedway.
