Modified, Stock Car qualifying begins at Boone 

BOONE, Iowa (Sept. 6) – Twenty Stock Car heats and 30 Modified heats set the stage for a pair of qualifying features in both divisions Wednesday at the IMCA Speedway Motors Super Nationals fueled by Casey’s.

What’s ultimately at stake this evening at Boone Speedway are the front eight starting spots on the inside row of championship events Saturday. Defending champion Elijah Zevenbergen starts on the pole of the 17th Stock Car heat while 2016 champion Ricky Thornton Jr. starts last in the 23 Modified heat.

Last-chance features decide the last six qualifiers for both Hobby Stock and Northern SportMod main events on Saturday.
