Manthey Racing

The 992.2 update for the Porsche 911 is an interesting case. On the one hand, we got the first-ever production hybrid 911 with the GTS earlier this year, but on the other, for the first time, we didn’t get a power bump on the track-focused GT3 model. The 992.2 lineup is slowly being updated as new 911 variants are coming out, and with the GT3 and GT3 Touring models being introduced on 18 October, we know the 992.2 GT3 RS should be around the corner. The most track-focused, normally-aspirated 911 will undoubtedly feature slightly more power out of its signature 4.0-liter flax-six. But what if you don’t want to wait? If you already have a 992.1 GT3 RS (or if you are considering one), Porsche Super Cup racing veteran and tuner, Manthey Racing based at the Nürburging has a solution for you. The company’s kit will take your 992.1 GT3 RS and infuse it with much-needed chassis and aerodynamic enhancements, which could make the 992.2 GT3 RS look like an unnecessary upgrade.

Let’s face it, the standard Porsche 992 GT3 RS is already a track monster. It’s a car that thrives on pushing limits, begging to be unleashed on the world’s most demanding circuits and race tracks. But for some drivers, "enough" is never enough. Enter the 2025 Porsche 911 GT3 RS MR, an extreme machine set to be unleashed by the combined might of Porsche and their long-time racing partner, Manthey Racing. I’ve been following the development of this car closely for a while now, and am absolutely blown away by the sheer amount of engineering that’s gone into it. Not too long ago, an un-camouflaged white prototype was spotted at the Nordschleife, giving us an up-close look at the possible performance upgrades that Manthey is cooking up. Based on what I’ve seen in the spy shots from CarSpyMedia, I wanted to highlight some of the features of this performance racing kit.

Manthey Racing was recently spied yet again testing their GT3 RS MR Prototype at the Nurburgring. The prototype has been wrapped in monochromatic camo this time around, but we can discern that the Manthey Racing team has worked their aerodynamic magic on this GT3. For starters, the rear wing looks like it belongs on an airplane, composed of a large fin, attached to where the rear windshield used to be. YouTuber Arc Driver recently dropped a video taking us through a detailed breakdown of all the modifications to the MR Prototype. Manthey Racing is known for Porsche-centric body kits and their in-house race team. Incidentally, the team recently claimed victory in the LM GT3 Category at Le Mans, and they did so in the Porsche GT3R Racecar.

The 2024 Le Mans served up quite a spectacle in the brand new LM GT3 class, with Porsche’ #91 Manthey EMA Porsche 911 GT3 R taking the win. Piloted by Richard Lietz, Morris Schuring, and Yasser Shahin, the race-spec 911 GT3 R took the checkered flag, etching Porsche’s and the Nürburing-based tuner’s name into the history books as the first manufacturer to win Le Mans with a GT3 car.

The Manthey Performance Kit unlocks the full potential of the Porsche 911 GT3 for the racetrack. Developed through a collaboration between Porsche and racing experts Manthey, it delivers sharper handling, faster cornering, and an unforgettable adrenaline rush. The Manthey Performance Kit isn’t just for professional drivers. Thanks to the kit’s enhanced handling and performance capabilities, it even helped Porsche factory driver Kévin Estre achieve a blistering lap time of 6:55.737 minutes on the Nürburgring Nordschleife. This transformation is achieved through the addition of 14 high-performance race parts that enhance suspension, aerodynamics, brakes, and other accessories. Years of racing experience, countless simulations, and extensive testing on the Nürburgring ensure each component is optimized for peak performance.
