ANTIOCH, Calif. — After a trial run last year, Antioch Speedway promoter Chad Chadwick will add the IMCA Sunoco Stock Cars to select Saturday night programs this season.

The stock cars join IMCA modifieds and sportmods at the Contra Costa County Fairgrounds venue.

“We had watched them race in the Midwest,” Chadwick said. “IMCA Stock Cars put on good racing, and we thought they’d be a good class to have here. This is a division that’s going to grow every year.”

The IMCA Speedway Motors weekly racing season is set to start on March 20. Stock Cars will share the spotlight with the modifieds and sportmods on May 29 and Sept. 4.
