GT4 cars will continue in the IMSA Michelin Pilot Challenge Grand Sport (GS) class in seasons to come thanks to a long-term extension of the agreement between the American promoter and SRO Motorsports Group.
The GT4 category has proven immensely successful in recent years, with big grids competing in a wide variety of series around the world. The concept, which was created and continues to be managed by SRO, has formed part of the GS class since 2017.
Speaking about the extended agreement, IMSA President John Doonan called GT4 "a tremendous customer racing platform that has been embraced by several manufacturers, at a price point that is attractive to many teams and drivers.
"We are pleased to work with Stéphane Ratel and his team at SRO to continue to provide GT4 action to IMSA fans for many seasons to come,” he added.
Stéphane Ratel said: “According to the global survey we conduct each year, GT4 has now surpassed all other GT categories in terms of cars racing worldwide. This success is thanks to the many championships and series on multiple continents that have adopted this well-priced yet highly competitive formula."
In addition to IMSA, a wealth of GT4 equipment can also be found in the GT4 European Series, Pirelli GT4 America Series, and Fanatec GT World Challenge Asia Powered by AWS. The next Michelin Pilot Challenge contest featuring the GS class will take place at Watkins Glen International on Friday 1 July.
