International GTSprint Series

The series born in 2010, as a support for the International Superstars Series, under the name of Superstars GTSprint. 23 cars raced the first round in Monza, and during the season the number of entries wandered around 17-18. Alessandro Bonetti and Maurizio Mediani won the title driving a Ferrari F430.

In 2011, the series obtained an international titration, with a consistent increase of participants. The following year, International Trophies for GTS-Cup and GTS-Open classes were created, but the cars on the grid fell dramatically and before the beginning of the 2014 season the series was finally folded. Thomas Schöffler was the last overall champion.

Since its birth, the series was focused on sprint races, as the name implies. There were two races for each weekend, consisting of twenty-five minutes + 1 lap. In 2012, the format changed into two races of thirty minutes, subsequently extended to one hour in 2013 with a mandatory pit stop in order to change the driver.

The series was open to grand tourer-style cars, broken into different classes based on power and weight. GTS-2, GTS-3 and GT4 classes were allowed respectively to the cars obeying their FIA regulations; GTS-Cup included cars used in manufacturer's one-make cup series; GT4-S was a subject of GT4 class and GTS-Open was open to grand tourer cars without precise regulations.

The scoring system was the same of International Superstars Series. Since 2012, an additional point was awarded to every driver in the starting grid of each race, which became two in 2013, with one point awarded as a "qualification point".
