Diet includes carbon fibre doors and hood.
In road-going specification, the Cayman GT4 weighs in at 1,340 kilograms (2,954 pounds). Its Clubsport track-only counterpart adopts a stripped-out interior cabin and other weight-savings measures to shave off 40 kg (88 lbs). Now, Manthey-Racing has managed to cut fat by a further 40 kg (88 lbs) thanks to lightweight doors and hood made from carbon fibre. In addition, the weight loss has been achieved by installing a polycarbonate windscreen and a lighter battery.
Besides putting the Cayman GT4 Clubsport on a strict diet, Manthey-Racing has developed a two-way adjustable race-spec suspension kit featuring linear bearings. Moreover, there’s an adjustable sway bar available, which MR says has improved the race car’s driving dynamics. Compared to the standard model, the upgraded variant comes with a bigger rear wing incorporating extended brackets.
With the upgrade kit in place, the Cayman GT4 Clubsport becomes an SRO-homologized GT4 race car, so it can compete in a wide variety of races in the GT4 category. It’s eligible to participate in the Pirelli World Challenge GTS as well as in IMSA’s Continental Tire Sports Car Challenge GS class.
Porsche Motorsport North America is exclusively in charge of selling the upgrade kit which makes the Cayman GT4 Clubsport an even more hardcore race car.
As for the road-going Cayman GT4, it’s bound to receive a facelift, and purists will be happy to hear that it will continue to be naturally aspirated, unlike the 718 Cayman which has made the switch to a turbocharged engine.
