There are cars that define performance. And then there are cars that define an era. The Porsche 718 Cayman GT4 RS Manthey Weissach belongs to the latter. A machine honed for the track yet legal for the road, it is one of the most extreme mid-engine Porsches ever created—and it will never be built again.
The Heritage of the Porsche GT4 RS Manthey
Porsche’s RS models have always carried a special aura. Lightweight, uncompromising, engineered to deliver motorsport technology directly to the road. From the 996 GT3 RS to the modern 911 GT3 RS, every RS badge tells a story of rarity and racing pedigree.
The 718 Cayman GT4 RS is unique in this lineage: it is the first and only Cayman to ever wear the RS badge. It represents the pinnacle of Porsche’s mid-engine philosophy, a philosophy that traces back to the legendary 550 Spyder of the 1950s. With its naturally aspirated 4.0-liter flat-six, revving to 9,000 rpm, the GT4 RS captures the raw mechanical purity that built Porsche’s reputation on road and track.
Why the Manthey and Weissach Packages Matter
Weissach Package: Porsche’s ultimate lightweight and motorsport-oriented option. It replaces standard materials with carbon fiber for the hood, roof, mirrors, and rear wing, adds a titanium roll cage, and shaves crucial kilograms. Inside, the Weissach package features Alcantara, exposed carbon, and details that underline its race-bred identity.
Manthey Kit: Developed by Porsche’s Nürburgring partner Manthey Racing, this package optimizes the GT4 RS for the track. It includes aerodynamic upgrades (larger front splitter, rear diffuser, wing endplates), lightweight forged wheels, stiffer suspension settings, and improved brake cooling. The result? A GT4 RS that’s even sharper, quicker, and more confidence-inspiring on the world’s most demanding circuits.
Together, these packages turn the GT4 RS into the ultimate expression of Porsche’s mid-engine philosophy—a street-legal machine carrying pure racing DNA.
End of an Era
This heritage makes the GT4 RS even more significant because Porsche has confirmed the end of production for the 982-generation 718 Cayman and Boxster in 2025. After October, no more combustion-powered mid-engine Porsches will leave Stuttgart. The age of the high-revving flat-six in the Cayman ends here, replaced in the future by electrification.
That means the GT4 RS Manthey Weissach isn’t just rare—it’s the last of its kind. A street-legal, naturally aspirated RS with Manthey Racing’s Nürburgring-bred setup will never be seen again.
Why It’s Almost Impossible to Get One
Even before Porsche announced the end, ordering an RS model was notoriously difficult. Allocations were limited, reserved for Porsche’s most loyal clients. Dealers worldwide were flooded with requests, and waitlists stretched beyond possibility. Many enthusiasts never even had the chance to place an order—production numbers were simply too low.
Today, with production closing, the chance of buying a new GT4 RS Manthey Weissach is virtually gone. They’ve already become instant collectibles, with secondary market values reflecting their rarity.
