Equipped with the Manthey Performance Kit
This 718 Cayman GT4 RS has been professionally upgraded with the Manthey Performance Kit---developed jointly by Porsche Motorsport and Nürburgring specialists Manthey to elevate track performance while maintaining road usability and factory warranty coverage. Installed by Porsche-certified technicians, this package refines every dynamic element of the GT4 RS to deliver sharper handling, faster lap times, and greater confidence behind the wheel.
Aerodynamics
A comprehensive aerodynamic upgrade increases overall downforce from 196 lbs. to 372 lbs. at 124 mph---nearly double that of the standard car. This is achieved through a larger, four-position adjustable rear wing mounted on swan-neck supports, a redesigned front underbody with optimized air guides, extended side blades, and carbon-fiber fender vents. Together, these components enhance stability, cornering precision, and high-speed balance on track or open road.
Suspension and Chassis
The Manthey coilover suspension is a four-way adjustable system co-developed with Porsche engineers. It allows individual adjustment of rebound and compression stages as well as ride height, enabling drivers to fine-tune the setup for specific track conditions. Front spring rates have been increased by 20% to improve steering response and reduce front-end dive under braking, while the rear setup has been calibrated for greater composure and traction on exit.
Braking System
Steel brake lines are part of the Manthey package, delivering a firmer pedal and improved brake modulation for consistent stopping power during extended track sessions. The system offers enhanced durability and more precise feedback through the pedal.
Additional Reinforcements
A carbon-fiber reinforced engine cover provides added rigidity to manage the increased aerodynamic load from the larger rear wing. The package also includes optimized alignment and geometry settings specific to the Manthey configuration, ensuring sharper turn-in and improved weight distribution at speed.
Performance Proven
Developed and tested extensively on the Nürburgring Nordschleife, the Manthey-equipped GT4 RS achieved a lap time of 7:03.121 minutes---over six seconds quicker than the standard car. The result is an extraordinary balance of grip, control, and feedback, transforming the GT4 RS into a precision instrument for drivers who want the ultimate evolution of Porsche's mid-engine platform.
Installed by Porsche technicians, fully integrated with factory systems, and preserving road legality and warranty coverage, this Manthey-equipped 718 Cayman GT4 RS represents one of the most track-capable Porsche road cars available today.
