The best Modified drivers from all over will descend upon Birch Run for their chance at the $7500 first-place prize, with $750 to start.  The I-75 will be the biggest Mod race in Mid-Michigan and nobody has the high-banks and grooves that these drivers will find at The Dixie.  Come out on Friday and catch the action of the Time Trial Challenge where drivers compete for the fastest lap times.  

On Saturday, the modified action is all day long.  Get there early so you have a good seat and catch the excitement as the rubber hits the road and the Mods tear up The Dixie. 

This race will be open to Howe
