Description MANTHEY RACING MR911GT2RS9912-2 Manthey Kit for PORSCHE 911 GT2 RS (991.2)
The Manthey Kit for the Porsche 911 GT2 RS (991.2) was developed in close cooperation between Porsche Development Centre Weissach and Manthey-Racing GmbH. The kit combines coordinated chassis, aerodynamic, brake, and cooling components to precisely adapt the vehicle’s performance to demanding track-day and high-speed driving conditions. All components are engineered to work as a unified system, ensuring consistent vehicle balance, stability, and durability under extreme loads.
The effectiveness of the kit was demonstrated in June 2021, when a road-legal 911 GT2 RS equipped with the Manthey Performance Kit achieved a Nürburgring Nordschleife lap time of 6:43.300 minutes, setting a new circuit record in the sports car category.
- Comprehensive performance upgrade developed jointly by Porsche and Manthey-Racing
- Optimised for track days and high-performance driving
- Significant increase in aerodynamic downforce and vehicle stability
- Motorsport-derived suspension and brake components
- All components designed to function exclusively as a complete kit
Specifications:
- Front Downforce at 200 km/h: increased from 49 kg to 70 kg
- Rear Downforce at 200 km/h: increased from 93 kg to 200 kg
- Total Downforce Increase: approximately 70%
- Additional Water Tank Capacity: +9.7 litres
Kit Components:
- Braided Brake Line Set. Brake line set with steel sheathing for better pedal feedback.Article no.: 99104480638.
- Coilover Kit (3-/4-way). 3-/ 4-way adjustable shock absorbers with aluminium shock bodies, including front and rear top mounts and lift adaptation (also available for vehicles without lift system).The development of the coilover suspension draws on both the expertise and technology gained from Porsche and Manthey's many years of experience in GT racing. An upside-down McPherson construction is used on the front axle. The suspension strut has a housing made of high-strength aluminium to ensure reliable and durable suspension control even in race track use. A 3-way adjustable damper unit and aluminium support bearings allow easy adjustment of the camber settings on the front axle. The independent compression stage adjustment in low and high speed is made on the external reservoir via the adjustment knobs, which can be operated without tools. The rebound stage can also be adjusted via an adjustment knob at the lower end of the shock absorber housing. If the vehicle is equipped with a standard front axle lift system, its function remains fully intact. An aluminium strut is used on the rear axle. The four-way adjustable damper (compression and rebound, in low and high speed) can be adjusted directly on the shock absorber housing using adjustment knobs that can be operated without tools. The base setup of the high-end suspension components was developed in countless laps on international race tracks, especially the Nürburgring Nordschleife, and meticulously tuned by Porsche and Manthey engineers.
