Tsunami RT, the Sanmarinese team present in both the International GT Open and the GT Cup Europe, will double its presence in the GT Open 500 at Monza, the endurance race closing the 2025 GT Open season.
Alongside the Porsche 911 R for championship regulars Johannes Zelger and Fabio Babini, Tsunami will field a second car, entrusted to Bashar Mardini and Alex Fontana. Both the Canadian-Emirati and the Swiss-Greek need no presentation, as they have been regular contenders of, and race winners in, the GT Sport-promoted series, and are familiar with Porsche machinery.
