MANTHEY RACING MR911GT2RS9912-1 Manthey Kit with Lightweight Wheel Set Magnesium for PORSCHE 911 GT2 RS (991.2)

Description MANTHEY RACING MR911GT2RS9912-1 Manthey Kit with Lightweight Wheel Set Magnesium for PORSCHE 911 GT2 RS (991.2)

The MANTHEY RACING MR911GT2RS9912-1 Manthey Kit with lightweight magnesium wheel set is a comprehensive performance upgrade developed specifically for the Porsche 911 GT2 RS (991.2). The kit was engineered in close cooperation between the Porsche Development Centre in Weissach and Manthey-Racing GmbH, integrating chassis, aerodynamics, braking, and cooling components into a precisely balanced system for track days and high-performance driving.

Through the coordinated interaction of suspension, aerodynamic elements, brake upgrades, and reduced unsprung mass, the kit further refines the performance characteristics of the 911 GT2 RS. In June 2021, a road-legal 911 GT2 RS equipped with the Manthey Kit set a Nürburgring Nordschleife lap record of 6:43.300 minutes on the 20.8 km circuit, demonstrating the effectiveness of this configuration.

• 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.
