IMSA officials have confirmed a long-term extension of an agreement with SRO Motorsports Group that could enable cars built to GT4 technical specifications to continue through at least the 2028 season.

Currently, GT4 cars are used in the IMSA Michelin Pilot Challenge GS class, while the sanctioning body is looking to add the platform alongside LMP3 cars as a replacement for IMSA Prototype Challenge beginning next year.

“The decision to incorporate GT4 into the Michelin Pilot Challenge GS class prior to the 2017 season continues to be a sound decision,” said IMSA President John Doonan. “Aside from the fields in some of the single-make series IMSA sanctions, the GS class routinely draws the largest fields at every race.

“It’s 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 Stephane Ratel and his team at SRO to continue to provide GT4 action to IMSA fans for many seasons to come.”

Eight different GT4 manufacturers, 37 different teams and 86 different drivers have competed in the GS class in at least one Pilot Challenge race. The GS class has averaged more than 28 cars per race through the first four races of the season.

“We are very pleased to confirm the long-term extension of our license agreement with IMSA for the GT4 category,” said SRO founder and CEO Stephane Ratel.

“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.

“With this announcement, we can look forward to GT4 remaining an important part of the IMSA Michelin Pilot Challenge in the Grand Sport class for many more years to come.”
