PEORIA, Ill. – A thunderstorm ascended over the Peoria Speedway just after the completion of the DIRTcar Summit Racing Equipment Modified Nationals C-main, forcing DIRTcar officials to postpone the remainder of Thursday night’s program to Tuesday, July 21.

The makeup program will resume with the DIRTcar Late Model C-main, Late Model feature, Summit Modified feature and Crate Modified feature.

Tri-City Speedway in Granite City, Ill., is next for the series on Friday.
