IMSA announced Friday a shakeup in the schedule for next year’s TUDOR United SportsCar Championship, which includes the addition of a 13th event at Kansas Speedway and other changes in the Prototype Challenge calendar.

With expected oversized grids, the PC class has been reduced to 10-round schedule, with the elimination of the Detroit and Canadian Tire Motorsport Park events in favor of a standalone race at Kanas Speedway on June 7.

“We already knew what we were going to do at Long Beach and thought we had a solution before for Detroit and ultimately had to make a minor adjustment there,” IMSA President and COO Scott Atherton told FOX Sports SPEED.

“All of this is the byproduct of the last three days of spreadsheet analysis and comparing which venues can accommodate which number of cars. Also, where it made the most sense to line up each of the classes and trying to make sure at the end of the process you had a similar race count for each of the categories.”

The Kansas event will be run as a combined race with IMSA Prototype Lites in a yet-to-be-announced sprint format. The same format is expected to be used for the VIR weekend, which will also see a joint PC/Lites race.

Additionally, changes have been made to the Mazda Raceway Laguna Seca weekend, with PC/GT Daytona and Prototype/GT Le Mans having separate races on the same day.

The remainder of the schedule remains unchanged for the P, GTLM and GTD categories.

Friday’s announcement equates to wholesale changes to the initial schedule, which was released less than one month ago.

Car capacity guidelines were also released for each race, with no more than 60 cars allowed to take part in the season-opening Rolex 24 at Daytona.
