After the successful Porsche Cayman GT4 Clubsport launch, MantheyRacing presented the Porsche GT4 Clubsport MR at the Total 24 Hours of Spa last month. The vehicle, based on a Porsche Cayman GT4 Clubsport racecar, has been fitted with a comprehensive upgrade kit developed by MantheyRacing. With the upgrade, the vehicle qualifies as an SROhomologized GT4 racing car, thereby allowing it to participate in national and international races in the GT4 category.
GT4 race series are gaining in popularity internationally. They provide for high quality, nail biting competition while simultaneously offering an attractive priceperformance ratio.
The technical highlights of the upgrade package include lightweight elements such as carbon fiber doors, carbon fiber front bonnet, a polycarbonate windscreen and an optional lightweight battery, which reduces the vehicle weight by around 40 kg (88 pounds). The twoway adjustable race suspension kit with linear bearings and an adjustable sway bar with blade adjustment further improves driving dynamics and adjustability. Performance optimization is rounded off with a rear wing larger than that of the basic vehicle, combined with extended wing brackets.
In the North American market, the Porsche GT4 Clubsport MR and Porsche Cayman GT4 Clubsport upgrade kit will be distributed exclusively by Porsche Motorsport North America. The car will be eligible for Pirelli World Challenge GTS class competition and in IMSA’s Continental Tire Sports Car Challenge GS class.
“We welcome the updated Porsche Cayman GT4 Clubsport package into our offerings for motorsport customers in North America. 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,” said Jens Walther, president and chief executive officer at Porsche Motorsport North America.
