Refining The Cayman GT4 Into A Precision Weapon
The Porsche 718 Cayman GT4 Manthey Kit represents the perfect evolution of precision and purpose. Built by Manthey Racing, a name synonymous with Nürburgring dominance and Porsche motorsport excellence, this kit unlocks the Cayman GT4’s hidden performance reserves with a blend of aerodynamic, suspension, and braking enhancements. The result is a car that remains civil on the street yet thrives in the high-demand environment of the racetrack, delivering a driving experience defined by balance, control, and mechanical harmony.
Every element of the Manthey Racing Manthey Kit for the Porsche 718 Cayman GT4 serves a purpose. The package refines aerodynamic flow, braking consistency, and suspension behavior under load. Developed with track-tested data, these upgrades translate directly to faster lap times and greater driver confidence. From the front air guide element to the rear Gurney flap and wing brackets, airflow management is a top priority. Each component reduces lift and increases downforce, ensuring the GT4 maintains poise and stability at high speed.
Suspension refinements come in the form of a fully adjustable coilover kit, tuned by Manthey engineers to enhance cornering response while maintaining comfort for street driving. This dual nature allows owners to drive to the track, compete all weekend, and return home with no compromises. Complementing the chassis are upgraded front and rear brake pads paired with braided steel brake lines that sharpen pedal feel and improve fade resistance during extended sessions. The enhanced brake cooling system further supports endurance under repeated heavy braking.
Every component in the Manthey Racing Manthey Kit for the Porsche 718 Cayman GT4 reflects the brand’s uncompromising motorsport heritage. The optional forged wheel set, available in 20×8.5 front and 20×11 rear configurations, reduces unsprung weight and strengthens overall responsiveness. Their construction ensures optimal rigidity under lateral load, allowing the tires to maintain consistent contact with the road surface through aggressive cornering. Lightweight mesh guards protect key aerodynamic openings from debris, balancing functionality with track-ready durability.
Attention to detail defines the Manthey approach. Each element has been tested under the demanding conditions of Nürburgring competition, refined until it meets the same standards expected of Porsche’s factory racing programs. The Manthey Racing Manthey Kit for the Porsche 718 Cayman GT4 brings that same pedigree to everyday enthusiasts who demand more from their machines.
Manthey Racing’s connection to Porsche runs deep. Since becoming majority-owned by Porsche AG, the company has worked directly alongside the automaker’s engineering teams to manage GT racing efforts in both the WEC and Nürburgring Endurance Series. The Manthey Racing Kit for the Porsche 718 Cayman GT4 draws directly from this expertise, translating decades of motorsport knowledge into a package engineered for real-world use.
The company’s success extends far beyond the track. Its reputation for precision-built, street-legal performance upgrades has made Manthey Racing a benchmark for Porsche enthusiasts worldwide. With more than 250 employees and extensive involvement in factory GT programs, Manthey Racing continues to shape the evolution of Porsche performance both on and off the circuit.
The Manthey Racing Manthey Kit for the Porsche 718 Cayman GT4 is available through Bulletproof Automotive, offering enthusiasts direct access to one of the most sophisticated Porsche upgrades on the market.
