Manthey's Porsche 718 Cayman GT4 RS Kit Hits U.S. Market

Porsche enthusiasts in the U.S. have reason to celebrate as the much-anticipated Manthey performance kit for the 718 Cayman GT4 RS is now available through authorized Porsche Centers. This kit, designed to amplify the car’s already remarkable track capabilities, can be professionally installed at these centers.

The Manthey Kit enhances the 718 Cayman GT4 RS by improving its aerodynamics and suspension. It introduces modifications like a doubled downforce at 124 mph and a 20 percent increase in front spring rates. These adjustments are bolstered by carbon fiber reinforcements and a larger rear wing, elevating the vehicle’s performance ceiling. Jörg Bergmeister showcased the potential of these enhancements by shaving over six seconds off the previous Nürburgring Nordschleife lap time, recording a blistering 7:03.121 minutes.

Under the hood, the GT4 RS is powered by a 493 hp 4L naturally aspirated flat-six engine, renowned for its robust racetrack credentials. The Manthey Kit includes a special coilover suspension that can be finely tuned for track conditions, featuring adjustable spring struts and the ability to tweak rebound and compression stages.

For those looking to further customize their experience, an additional package is available, which enhances aerodynamics with carbon fiber front fender louvers and an augmented rear ducktail spoiler. This package increases rear axle downforce by up to four percent in its most aggressive setting.

The complete Manthey Kit is priced at $53,946 USD — excluding installation. The additional aerodynamics package is available for $5,890 USD.

Additionally, Porsche’s Experience Centers in Atlanta and Los Angeles will feature driving programs that include the upgraded 718 Cayman GT4 RS, providing the perfect opportunity for potential buyers and enthusiasts to experience the enhancements firsthand.
