The series, founded in 2009 by the SRO Group as the Dutch GT4 Championship, uses grand tourer cars conforming to the Fédération Internationale de l'Automobile GT4 regulations.

In recent years races have also been added in Germany and Slovakia.

Dominant cars in the series include the BMW M3, Porsche 911, Chevrolet Corvette, Chevrolet Camaro, Toyota GT-86, Lotus Evora, Ginetta G50, and Aston Martin V8 Vantage.

Events follow a format of two 25 minutes races, followed by a 50 minutes final race, although some events shared with other series use a modified format.

Dutch driver Ricardo van der Ende is the defending series champion, driving for Racing Team Holland BMW.
