Manthey Porsche 911 GT3 RS

Precision Engineered for Performance

A Porsche-backed specialist in high-performance tuning and endurance racing, renowned for their Nürburgring dominance and engineering excellence, Manthey have collaborated with Porsche to develop a comprehensive upgrade package for the 992.1-generation Porsche 911 GT3 RS.

Developed at Porsche’s Weissach Development Center and tested on circuits such as the Nürburgring Nordschleife, this Manthey Performance Kit optimizes aerodynamics, suspension, and braking systems—further sharpening the capabilities of an already extreme track-focused machine.

Engineering the Manthey 911 GT3 RS

Aerodynamics: Maximizing Downforce Without Compromising Drag

Aerodynamic performance is at the core of the Manthey 911 GT3 RS, with modifications aimed at increasing downforce while maintaining efficiency. Manthey engineers fine-tuned key components to provide better stability at high speeds.

  • Front Splitter and Dive Planes: A larger front splitter and reshaped flics improve airflow, enhancing stability during turn-in and reducing lift at high speeds.
  • Revised Rear Wing & Diffuser: Manthey’s split DRS rear wing, featuring larger endplates, optimizes rear downforce, while the extended rear diffuser helps manage airflow for greater high-speed grip.
  • Carbon Fiber Enhancements: A lightweight carbon rear window replaces the standard glass unit, reducing weight by 25%, while an FIA-derived shark fin (inspired by Porsche’s 963 LMDh race car) enhances cornering stability.

The result? The Manthey kit increases downforce by 20% without adding drag, allowing the 911 GT3 RS to generate over 2,200 lbs. of downforce at 177 mph. This ensures superior handling through medium and high-speed corners—essential for track performance.

Suspension: Race-Tuned Adjustability

Suspension development for the Manthey kit resulted in a semi-active coilover system designed for extreme precision.

  • Increased Spring Rates: The front axle is stiffened by 30%, and the rear axle by 15%, improving body control under heavy braking and high-speed cornering.
  • Adaptive Coilovers: Equipped with four wheel sensors and three body acceleration sensors, the system continuously adjusts damping rates for maximum grip.
  • Track-Ready Customization: In Normal, Sport, and Track modes, suspension settings can be further manually adjusted via steering wheel controls, allowing drivers to fine-tune handling for different circuits.

With these refinements, the Manthey 911 GT3 RS delivers greater high-speed stability, sharper turn-in response, and improved corner-exit grip—essential for achieving record-breaking lap times.

Braking System: Motorsport-Level Stopping Power

Manthey’s track-focused enhancements extend to braking, addressing the thermal and performance demands of endurance racing.

  • Braided Steel Brake Lines: Enhance pedal feel and provide quicker response under heavy braking.
  • Racing Brake Pads (Optional): Designed for improved bite and fade resistance, ensuring consistent performance during extended track sessions.

These refinements ensure that the 911 GT3 RS with the Manthey Kit maintains exceptional braking performance even under the most demanding track conditions.

Track-Developed, Nürburgring-Proven

Manthey’s legacy at the Nürburgring Nordschleife speaks for itself. Their 992 GT3 with the Manthey kit recorded a 6:55.737 lap, making it one of the fastest street-legal cars ever to lap the Green Hell.

Given the extensive aero and suspension optimizations, the Manthey 992.1 GT3 RS is expected to challenge, if not surpass, its own record. Nicolas Raeder, Managing Director of Manthey Racing GmbH stated:

“Over a period of two years, we worked together with Porsche engineers on the new Manthey Kit for the 911 GT3 RS and tested it over several thousand kilometres on European racetracks and on the Nürburgring Nordschleife.”

With its development rooted in real-world motorsport conditions, this package represents the pinnacle of Porsche factory-approved track upgrades.

Availability

The Manthey Performance Kit for the Porsche 911 GT3 RS 992.1 is now available in the U.S. and Europe, allowing enthusiasts to transform their GT3 RS into the ultimate track weapon.

For those who demand the absolute best in track performance, Manthey’s expertise offers a factory-approved solution backed by Porsche’s motorsport heritage. Whether it's shaving seconds off lap times or achieving unparalleled cornering speeds, this upgrade package ensures that the 911 GT3 RS remains a dominant force on the track.
