The Porsche Cayman GT4 Clubsport is now eligible for GT4 competition worldwide, via an upgrade kit, which was unveiled last weekend at Spa-Francorchamps.

Manthey Racing presented the Porsche GT4 Clubsport MR, which puts the car into full SRO GT4 compliance, while offering an “attractive price-performance ratio,” according to the German manufacturer.

The upgrade kit, developed by the Porsche-owned team, includes new carbon fiber doors and hood, a polycarbonate windshield and optional lightweight battery, which reduces the vehicle weight by 40kg.

A two-way adjustable race suspension kit and adjustable sway bar has also been developed, along with a larger rear wing and extended wing brackets.

The car and upgrade kit will be distributed exclusively by Porsche Motorsport North America in the North American market and will be eligible for competition in both the IMSA Continental Tire SportsCar Challenge GS class and Pirelli World Challenge GTS category.

“We welcome the updated Porsche Cayman GT4 Clubsport package into our offerings for motorsport customers in North America,” said Porsche Motorsport North America President Jens Walther.

“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.”

Cayman GT4 Clubsports currently competing in Continental Tire Challenge are expected to continue to be eligible this year, although IMSA is poised to adopt full GT4 regulations to the class for next year.
