2025 Porsche 911 GT3 RS Gains Manthey Kit for Track Dominance
Porsche enthusiasts have something new to look forward to: the 2025 Porsche 911 GT3 RS with the Manthey Kit. This collaboration between Porsche's Weissach Development Center and the Manthey engineers in Meuspath promises to elevate the already formidable GT3 RS to new heights on the racetrack, thanks to significant enhancements in aerodynamics, suspension, and braking systems.
Aerodynamic Enhancements for Unmatched Downforce
The Manthey Kit transforms the 911 GT3 RS with extensive aerodynamic modifications, allowing it to generate over 1,000 kilograms (approximately 2,205 pounds) of downforce at 285 km/h (177 mph). Key changes include a significantly larger front spoiler lip supported by carbon fiber reinforcements, redesigned wheel arch Gurney flaps, and additional dive planes on each side of the front bumper. These features collectively boost downforce on the front axle, improving grip and stability in high-speed corners.
At the rear, a carbon fiber shark fin, inspired by the Le Mans-winning 963, replaces the rear window, enhancing cornering stability by directing airflow more effectively. The addition of roof fins helps channel hot air away from the rear intake, ensuring optimal engine cooling. The split carbon fiber DRS (Drag Reduction System) wing, along with enlarged end plates, significantly increases rear axle downforce without increasing drag. Complementing these changes are carbon fiber 'aerodisc' wheel covers that reduce air resistance and contribute to the car's overall aerodynamic efficiency.
Semi-Active Suspension Tailored for the Track
The Manthey Kit introduces a semi-active coilover suspension system with adjusted spring rates—30 percent stiffer at the front and 15 percent at the rear—to handle the increased downforce. The system utilizes four wheel-acceleration sensors and three body-acceleration sensors, along with a new control unit, for precise damper tuning. The shock absorbers feature independent valves for compression and rebound, allowing for instant adjustments based on driving conditions. Drivers can choose from different damping profiles in Normal, Sport, and Track modes, with the option to fine-tune settings in Track mode via steering wheel controls.
Optimized Braking for Demanding Track Use
Recognizing the intense demands of track driving, the Manthey Kit upgrades the GT3 RS's braking system. Steel-sheathed brake lines provide a more direct pedal feel and quicker response. For models equipped with the Porsche Ceramic Composite Brake (PCCB) system, optional racing brake pads are available. These pads offer consistent performance across a wide temperature range, reduce fading, and enhance control precision, contributing to better wear resistance for both pads and discs.
Comparing to the 911 GT3 with Manthey Performance Kit
The enhancements brought by the Manthey Kit to the 911 GT3 RS are a step above those made to the standard 911 GT3 with the Manthey Performance Kit. While the GT3 benefited from improved aerodynamics, reduced unsprung mass through optional lightweight forged wheels, and a faster Nürburgring lap time by 4.19 seconds (completing it in 6:55.7 minutes), the GT3 RS with Manthey Kit promises even greater performance gains. The GT3 RS's already aggressive aero package is further amplified, resulting in unparalleled downforce figures, and its suspension and braking systems are optimized for even higher track demands.
Personalization Options and Pricing
Owners looking to add personal touches to their 2025 911 GT3 RS can choose from a range of accessories. Options include illuminated carbon fiber door sill guards with Manthey lettering, LED door projectors, and decals for the aerodiscs in various colors. Additionally, Manthey branding can be applied to the doors, and a towing eye, available in red, black, or yellow, can be fitted for track use.
The Manthey Kit for the 911 GT3 RS is priced from €76,911 (approximately $85,000 USD at current exchange rates), excluding country-specific taxes and installation costs at Porsche Centers. The kit will be available in European markets starting January 2025 and will reach the U.S. and other markets by March 2025. Importantly, installation of the Manthey Kit does not affect the vehicle's manufacturer warranty.
Pushing the Limits of Performance
Porsche Brand Ambassador Jörg Bergmeister notes that with the Manthey Kit, the 911 GT3 RS exhibits significantly improved performance on the racetrack, especially in medium-speed corners. The car demonstrates reduced dive, pitch, and roll, offering a more stable aerodynamic platform and consistent downforce under all driving conditions. Manthey Racing's Managing Director, Nicolas Raeder, adds that extensive testing over thousands of kilometers on European tracks, including the Nürburgring Nordschleife, has shown promising data with significant lap time improvements.
Final Thoughts: A Track-Day Marvel
The 2025 Porsche 911 GT3 RS with Manthey Kit represents the pinnacle of Porsche's track-focused engineering for road-legal vehicles. By incorporating advanced aerodynamics, a finely tuned suspension, and enhanced braking components, Porsche and Manthey have created a machine that not only pushes the boundaries of performance but also offers drivers the opportunity to experience motorsport technology firsthand. For enthusiasts seeking the ultimate track-day car that can still be driven home, the new GT3 RS with Manthey enhancements stands as a compelling option.
