The Porsche 911 GT3 RS is a car that already sets hearts racing with its track-ready performance, but Manthey Racing has taken things to the next level. Known for pushing the limits of engineering and aerodynamics, Manthey Racing has introduced a Porsche-approved performance kit designed to make the GT3 RS even more of a beast on the track. This isn’t just about aesthetics—it’s a complete package of aerodynamic, suspension, and braking upgrades that takes lap times and driving experience to another level.
Whether you’re aiming to conquer the Nürburgring or simply want the sharpest weapon in your garage, the Manthey upgrade brings track-day dreams to life. Let’s dive into what makes this kit so special.

A New Standard in Aerodynamics
The standout feature of the Manthey Racing package is its suite of aerodynamic enhancements. It begins with a bold move: the replacement of the GT3 RS’s rear window with a carbon fiber panel that’s 25% lighter than the original. While this might seem like a small change, it’s far more than just weight-saving. This panel integrates a shark fin antenna, directly inspired by Porsche’s endurance racing legend, the 963.
This aerodynamic element works with six smaller fins mounted on the roof, creating an intelligent airflow system. These fins guide hot air from the front-mounted radiators away from the car, ensuring the rear intakes pull in cooler air. Cooler air means better engine efficiency—critical for high-speed track performance.
Manthey also revamped the carbon rear wing, equipping it with newly designed endplates to increase downforce. Complementing the wing is a larger rear diffuser, which optimizes airflow beneath the car to further improve stability at high speeds. To reduce drag, the wheels are fitted with carbon fiber aerodisc covers, which not only look cool but also minimize turbulence.
The result? The Manthey GT3 RS generates a staggering 2,204 pounds of downforce at 177 mph, making it one of the most aerodynamically capable track machines in its class.
Sharper Suspension and Braking Precision
Aerodynamics is only part of the equation. Manthey has significantly upgraded the GT3 RS’s suspension to harness all that downforce. The front axle spring rates have been stiffened by 30%, while the rear sees a 15% increase. This translates to sharper cornering, reduced body roll, and a more responsive track feel.
The shock absorbers have been fine-tuned to handle the increased downforce and stiffer springs, ensuring the car remains balanced even during aggressive manoeuvres. And it doesn’t stop there—cars equipped with ceramic-composite brakes gain access to racing brake pads, designed to provide exceptional stopping power and fade resistance, even under extreme conditions.
Track-Ready Refinements and Subtle Touches
While the aerodynamic and performance upgrades steal the spotlight, Manthey has also added several smaller refinements to enhance the overall experience. Carbon fiber door sill guards add a touch of luxury, while LED door projectors and optional decals provide a customizable flair. There’s even a towing eye for those planning to use the car exclusively on the track, though it’s not legal for road use.
These thoughtful additions ensure that the Manthey package is as much about driver satisfaction as it is about outright performance.
The Nürburgring Ambitions
Manthey Racing has a history of chasing records at the Nürburgring, and this upgraded GT3 RS is no exception. The stock GT3 RS already set an impressive lap time of 6:49.32 in October 2022 on the 12.92-mile (20.8-kilometer) configuration of the iconic track. Manthey’s upgraded car aims to go even faster.
While testing has been delayed due to unfavorable weather, Manthey is confident that the revised GT3 RS can come close to the 6:43.30 benchmark set by a previous-generation GT2 RS equipped with their components. With additional development and ideal conditions, it’s only a matter of time before the car rewrites the record books.
Availability and Pricing
The Manthey upgrade kit will be available in the European Union starting January 2024, with non-EU regions following in March. While pricing for the GT3 RS kit hasn’t been disclosed, it’s worth noting that the Manthey package for the 718 Cayman GT4 RS starts at $53,946, excluding installation costs. Expect the GT3 RS package to fall within a similar range.
This package promises a significant return in unparalleled track-day performance for owners willing to invest in their car’s ultimate potential.
