911 GT3 (992)

Tailored exclusively for use on the race track and on track days, the 911 GT3 Manthey Kit made it possible for Porsche factory driver Kévin Estre to clock a lap time of 6:55.737 minutes on the legendary Nürburgring Nordschleife. The already athletic 911 GT3 benefits further from new aerodynamics, chassis adjustments, brake system improvements, and even a lightweight set of alloy wheels. Collectively, this package of performance components has been exhaustively tested and tuned to deliver uncompromising performance.

Aerodynamics Package

Perfected in the wind tunnel of the Porsche Development Center in Weissach, these exterior elements increase downforce and improve high-speed stability. Highlights include a larger rear wing spoiler, flow-optimized rear diffuser with lengthened fins, and authentic carbon fiber accents featuring a painted Manthey logo.

Coilover Suspension

Developed in the most demanding racing environments, this specialized coilover suspension balances drivability with comfort. It features fully aluminum 4-way damping force-adjustable spring struts, lightweight components, and adjustable damping forces to deliver perfected handling.

Brake Wire Harness with Steel Sleeve

Providing more direct pedal feedback and faster response time, these brake components provide maximum stopping power. Also available are racing brake pads with a unique wear-resistant compound that delivers reliable performance across a wide temperature range.

Wheel Set

With the goal of reducing unsprung weight, the optional 20/21-inch lightweight Manthey wheel set is equal parts style and function. In total, a weight reduction of 16.1 pounds per set provides noticeable benefits behind the wheel. Finish options include Brilliant Silver, Black (satin-gloss), and Dark Silver.

718 Cayman GT4 RS

Just like any precision instrument, the Porsche 718 Cayman GT4 RS is a purpose-built sports car that’s already earned a race-winning pedigree in its own right. With the addition of the Manthey Kit, this iconic Porsche vehicle transforms into a pure performance machine with an emphasis on lower lap times and improved driving agility. Tested and perfected on the Nürburgring Nordschleife, the 718 Cayman GT4 RS unlocked its full potential with a stunning lap time of just 7:03.121 minutes.

Aerodynamics Package

Sharpened, chiseled, and sculpted to slice through the air – the functional aerodynamics package increases downforce for maximum high-speed stability. Specialized air curtains and flaps tucked within the wheel housings improve ventilation as well. A carbon fiber front diffuser directs air under the vehicle for composed grip in the corners. At the rear, you’ll find a stunning fixed carbon fiber rear wing with an integrated Gurney Flap.

Coilover Suspension

Balancing road-going comfort with on-track poise, this remarkable coilover suspension features upside-down suspension struts, adjustable force struts, and adaptive spring rates to dial in handling. The system is available on vehicles equipped with or without the front axle lift system, making it easily adaptable to your specific needs.

Brake Line Set with Steel Sleeve

Tested and co-developed by Manthey on the Nürburgring Nordschleife, this brake line set provides more responsive pedal feedback for lightning-quick response time. Also available is a set of dedicated racing pads with increased wear resistance and superior control.
