With the spotlight still on the newly refreshed Porsche 911 GT3, enthusiasts are eager for what’s next.
While we await the updated RS model, Manthey, Porsche’s trusted motorsport partner, has taken the outgoing 911 GT3 RS to the next level with a factory-approved aerodynamic and performance kit.
This isn’t just a cosmetic enhancement—a meticulously engineered upgrade designed for drivers who demand the best on the track.
A Legacy of Collaboration
Manthey’s reputation for enhancing Porsche’s road and race cars is unmatched. Since Porsche acquired a 51% stake in Manthey in 2013, the partnership has delivered significant advancements in track performance. The latest aerodynamic kit for the 911 GT3 RS is no exception, featuring upgrades that push the limits of what the Rennsport model can achieve.
This collaboration also ties into Porsche’s broader approach to track-focused vehicles. Models like the Porsche 911 Carrera T, which emphasize lightweight construction and sharp handling, showcase Porsche’s ethos of blending usability with performance. Manthey’s kit for the GT3 RS extends this philosophy but leans heavily into the extreme end of the spectrum, perfect for the Nürburgring or other demanding circuits.
Major Aerodynamic Overhauls
Carbon Fiber Innovations
One of the most striking changes is the removal of the standard rear window. In its place, Manthey installs a 25% lighter carbon fiber panel. This panel has a shark fin antenna inspired by the Porsche 963 endurance racer, adding form and function. Six smaller fins on the roof further optimize airflow, guiding hot air from the front radiators away from the car and ensuring cooler air intake at the rear.
Redesigned Rear Wing and Diffuser
The already imposing rear wing gets an upgrade with new endplates, increasing downforce for better high-speed stability. Below, the diffuser has been enlarged to enhance aerodynamic efficiency further.
Aerodisc Wheel Covers
Carbon fiber aero disc wheel covers reduce air resistance while lending the car a distinct racing aesthetic. Together, these aerodynamic enhancements enable the GT3 RS to generate over 2,204 pounds of downforce at speeds of 177 mph—figures that rival even professional race cars.
Suspension and Brake Upgrades
Manthey didn’t stop at aerodynamics. The suspension system receives significant improvements to handle the increased downforce and deliver razor-sharp handling.
- Stiffer Springs: Front spring rates are increased by 30%, while the rear sees a 15% improvement, ensuring better balance and responsiveness.
- Shock Absorber Tuning: Custom shock absorbers are designed for aggressive cornering and improved stability.
- Racing Brake Pads: Optimized for cars equipped with ceramic-composite brakes, these pads offer greater durability and stopping power under intense conditions.
These upgrades build on Porsche’s tradition of offering precise, driver-focused cars. Even models like the Carrera T, known for their direct steering and engaging dynamics, share the same DNA, making every 911 a standout performer.
Track-Tested for Perfection
Manthey spent two years developing this kit, logging thousands of miles on European racetracks to refine every detail. The Nürburgring was central to this testing, with Manthey aiming to beat the 6:49.32 lap time set by the standard GT3 RS in October 2022.
To put this in perspective, the Porsche 911 GT3 RS already pushes the boundaries of what a road-legal car can achieve. For comparison, the Porsche 911 Carrera T, while not as extreme, embodies the essence of Porsche’s performance pedigree, offering an accessible yet thrilling driving experience. Manthey’s enhancements aim to bridge the gap between the stock GT3 RS and Porsche’s endurance race cars.
Beyond the Numbers
The Manthey kit isn’t just about shaving seconds off lap times and delivering a complete track experience. Porsche owners can further personalize their cars with a range of accessories included in the package:
- Carbon fiber door sill guards with illuminated branding.
- Unique body decals for added flair.
- LED door projectors.
- A towing eye (track-use only).
These additions underline the attention to detail that defines Manthey’s work.
The Nürburgring Challenge
The Nürburgring lap time is a badge of honor for performance cars, and Manthey is determined to make its mark. The goal is to close in on the 6:43.30 lap achieved by a previous-generation 911 GT2 RS equipped with Manthey components.
This task is monumental, considering the GT3 RS must balance road legality with track dominance. Yet, if there’s one brand capable of such a feat, it’s Porsche, especially with Manthey in its corner.
Availability and Pricing
The Manthey aerodynamic kit is available for order now. European customers will start receiving deliveries in January, while those outside the EU will need to wait until March. While pricing for the GT3 RS kit hasn’t been disclosed, the 718 Cayman GT4 RS package starts at $53,946 in the U.S., excluding installation fees.
Porsche’s Performance Ecosystem
Introducing this Manthey kit isn’t just a win for GT3 RS owners—it’s a testament to Porsche’s dedication to evolving its performance lineup. Models like the Carrera T remind us that Porsche caters to many enthusiasts, from those seeking pure driving pleasure to those chasing lap records.
As we await the next-generation GT3 RS, Manthey’s upgrade reminds us what’s possible when passion for performance meets engineering excellence. For track-day enthusiasts, it’s an opportunity to own a piece of Porsche’s motorsport legacy—one that’s poised to leave its mark on circuits worldwide.
