Porsche introduced a race car based on its limited edition Cayman GT4 for the 2016 motorsport season.

Ahead of the 2017 season, there’s a new, more hardcore version.

It’s called the Cayman GT4 Clubsport MR, and it was developed by German motorsport and engineering firm Manthey-Racing.

Manthey has years of experience in sports car racing and is Porsche’s official partner in the GTE category of the World Endurance Championship.

For the Cayman GT4 Clubsport MR, the engineers started with the Cayman GT4 Clubsport but reduced the weight a further 88 pounds via carbon fiber body panels (hood and doors), a polycarbonate windscreen and lightweight battery. They also added a larger rear wing and uprated suspension with more adjustment.

With the upgrades, the car now qualifies for SRO-sanctioned GT4 events. In the United States it’s also eligible for Pirelli World Challenge GTS class competition and in IMSA’s Continental Tire Sports Car Challenge GS class.

The Cayman GT4 Clubsport and upgraded GT4 Clubsport MR is available now through Porsche Motorsport North America. Other markets have to order it from Porsche Motorsport.

“We welcome the updated Porsche Cayman GT4 Clubsport package into our offerings for motorsport customers in North America,” Porsche Motorsport North America CEO Jens Walther said in a statement. “Customer racing is the structure on which all sports car racing is built, and as the GT3 and ACO classes become more manufacturer-oriented, the GT4 category provides a more attainable entry point to compete in sports car racing.”
