Manthey Reveals 30th Anniversary Limited-Edition Porsche Race Cars
German performance specialist Manthey is celebrating three decades of motorsport engineering with two exclusive Porsche race cars designed for enthusiasts and collectors. The Porsche 911 GT3 Cup MR 30 and Porsche 718 Cayman GT4 RS Clubsport MR 30 each will be limited to just 15 examples, bringing together years of track-tested development, lightweight materials and bespoke anniversary detailing.
The two special editions made their world debut on Oct. 9, 2026, at the DTM finale at Hockenheim. More than commemorative collector cars, both models reflect Manthey's philosophy of developing technical solutions around real-world racing demands, with each component refined through competition and testing on the Nürburgring Nordschleife and other international circuits.
The result is a pair of highly specialized machines that represent the latest evolution of two important vehicle ranges within Manthey's Race Cars division.
Porsche 911 GT3 Cup MR 30
The Porsche 911 GT3 Cup MR 30 builds on Manthey's longstanding Cup MR development program, which has focused on refining engine performance, aerodynamics, suspension, cooling and vehicle balance. Based on a comprehensively revised Porsche 911 GT3 Cup (992.1), the anniversary edition brings those development priorities together in a single package.
At its heart is a water-cooled, 4.2-liter six-cylinder boxer engine producing 560 PS (412 kW). Power reaches the rear wheels through a sequential six-speed gearbox, giving the special edition a significant performance focus.
The larger engine is complemented by an aerodynamic and cooling package that has already demonstrated its capabilities in customer racing on the Nürburgring Nordschleife. The underlying development version recorded a lap time of 7:58.605 minutes on the 24.358-kilometer NLS track configuration, despite producing less power than the anniversary model.
Lightweight construction is central to the car's design. The front end, including the wings and hood, along with the rear bodywork, wheel arch extensions, rear lid and rear wing, uses recycled carbon fiber. These components are designed to optimize airflow and increase downforce while contributing to the car's overall performance.
A central radiator layout delivers aerodynamic benefits while improving exhaust airflow and reducing the risk of radiator damage in the event of contact. An optimized brake-cooling system, featuring significantly enlarged air inlets, also helps reduce thermal strain on components and extend their operating life.
Additional aerodynamic enhancements include a front splitter with an integrated underbody, extra aerodynamic flicks and a newly developed rear wing with enlarged end plates and modified mounting. The revised wing mounting also allows the integration of an aerodynamically optimized air intake.
The car's wider stance is enabled by wheel arch extensions that accommodate a track-width increase of 20 millimeters at the front and 50 millimeters at the rear. Completing the package is a lightweight wheel set produced at Manthey's own forged-wheel facility. Finished in an exclusive 30th-anniversary design, the wheels save an additional 3.8 kilograms.
A six-way adjustable coilover suspension with optimized spring rates and modified front and rear axle kinematics rounds out the mechanical revisions. The anniversary details continue inside the cabin, where a bespoke ‘30 Years of Manthey’ badge and embroidered anniversary lettering on the seats distinguish the limited-edition model.
Porsche 718 Cayman GT4 RS Clubsport MR 30
The Porsche 718 Cayman GT4 RS Clubsport MR 30 celebrates a decade of Cayman-based race car development at Manthey. It also marks the final stage of a platform that has played a defining role in the company's Race Cars division.
The development story began with Manthey's homologation kit for the first Porsche Cayman GT4 Clubsport (981), which enabled the car to compete in GT4 racing series worldwide. Manthey also launched the Cayman GT4 Trophy by Manthey Racing, now known as the Porsche Endurance Trophy Nürburgring, to provide a competitive platform on the Nordschleife.
Subsequent projects based on the 981 and 718 generations included the Trackday MR, the 718 Cayman GT4 RS Clubsport Leichtbau and customer racing developments for Nordschleife competition. The MR 30 consolidates the lessons learned across that decade of engineering and testing.
Lightweight construction and comprehensively revised aerodynamics define the anniversary model. Extensive carbon-fiber body components, paired with a special lightweight wheel set manufactured in-house, reduce weight by a total of 5.7 kilograms compared with the base model. The 500 PS race car is designed to make the most of those weight savings and its aerodynamic refinements.
Carbon-fiber components include the fenders with lightweight headlights, a hood with a central radiator vent, the front bumper and splitter, and a redesigned rear section incorporating a rear bumper, a trunk lid with a lightweight window and a rear wing. A carbon-fiber diffuser and additional front flicks provide further downforce.
As with the 911 GT3 Cup MR 30, the Cayman uses a central radiator layout and optimized brake cooling. Its brake air ducts draw on developments from the Porsche 911 GT2 RS Clubsport EVO.
The car's development has been continuously tested and refined under real racing conditions. During validation, the vehicle concept achieved a top-20 overall finish at the 24 Hours of the Nürburgring, providing further evidence of its performance under demanding endurance-racing conditions.
Exclusive details distinguish the anniversary edition from the standard model. The rear-wing end plates carry the ‘30 Years Anniversary’ logo, while a ‘30 Years Manthey’ badge features the individual model number. The headrests also display the anniversary logo.
Exclusive Anniversary Design, Limited Production
Both Manthey MR 30 models feature an anniversary livery developed specifically for the company's 30th year. The show cars combine a white base with red accents and a reinterpreted streamlined design, drawing directly on Manthey's corporate colors and motorsport heritage.
The 911 GT3 Cup MR 30's white-painted chassis takes inspiration from historic Porsche race cars. Across both models, the graphic elements connect the company's heritage with its future, drawing on the anniversary livery of Manthey's No. 911 car at the 24 Hours of the Nürburgring.
Rather than simply revisiting historic designs, the anniversary models reinterpret familiar Manthey styling cues. The resulting aesthetic is intended to reflect the company's development philosophy while offering a glimpse of the design language that will shape future racing programs and engineering projects.
Production is limited to 15 examples of each model, for a combined total of 30 cars in recognition of Manthey's 30th anniversary.
Order requests will be accepted through Oct. 30, 2026, after which Manthey will make the final allocation because of the limited production run. Deliveries of the Porsche 718 Cayman GT4 RS Clubsport MR 30 are scheduled to begin in November 2026, while deliveries of the Porsche 911 GT3 Cup MR 30 will commence in the first quarter of 2027.
Pricing has not been revealed, but both cars will be available to buy in the United States, offered through Porsche Motorsport North America.
Three Decades of Motorsport Expertise
For Manthey, the two anniversary editions represent more than a milestone. They bring together three decades of engineering experience, competitive development and customer-focused motorsport projects.
“Both cars exemplify the way development takes place at Manthey: driven by specific customer requirements and motorsport projects. They were not created to celebrate an anniversary, but for use on the racetrack. The fact that we are now able to offer the results of these two development paths as limited-edition special models makes them a particularly fitting way to conclude our 30th anniversary year,” says Nicolas Raeder, managing director of Manthey Racing GmbH.
Helmut Brakhage, director of Race Cars at Manthey, also emphasizes the significance of the two models in the company's development history.
“30 years of Manthey means three decades of experience in global motorsport, three decades of development and three decades of total enthusiasm for our products,” he said. “We want to express this through these two special edition models. The 718 Cayman GT4 RS Clubsport MR 30 is the flagship of the mid-engine racing car that has enjoyed success for over 10 years. A vehicle concept that we were privileged to help shape and which we are celebrating appropriately at the end of the model range.”
With just 30 cars planned between them, the Porsche 911 GT3 Cup MR 30 and 718 Cayman GT4 RS Clubsport MR 30 offer a distinctive expression of Manthey's engineering philosophy. Their combination of competition-developed performance, carbon-fiber construction, specialized aerodynamics and individually numbered anniversary details makes them a fitting tribute to three decades of motorsport development.
