The Manthey kit for the 911 GT3 RS (Type 991 II) was developed in close cooperation between the Porsche Development Centre in Weissach and Manthey-Racing GmbH. Thanks to coordinated chassis, aerodynamics and braking components, it was possible to tailor the breathtaking performance of the 911 GT3 RS even more precisely to the requirements of track days and tourist drives.

In other words: 6:54.340 minutes for the approximately 20.8 kilometers of the Nürburgring-Nordschleife. During this impressive time, Porsche works driver Kévin Estre lapped the "Green Hell" in April 2021 in a GT3 RS with an identical kit.

Aerodynamic package

The downforce level of the vehicle is increased by the installation of various components: additional air deflectors are used in the area of the front wheels, flaps on the front apron and a new rear wing made of carbon.

Aerodiscs on the rear wheels, which are also made of carbon, reduce turbulence in the rear end and further increase aerodynamic efficiency. In order to take into account the higher aero load caused by the rear wing, the rear end is massively stiffened. The rear wing itself is connected directly to the body with the help of special supports (GT3 RS without Manthey Kit: connection of the wing to the boot lid). The aerodynamics package was tested, among other things, in the wind tunnel in Weissach, which is still one of the most modern of its kind: The eight-meter diameter blower has extremely light carbon blades and can generate wind speeds of up to 300 km/h in the test section on the tested vehicle.

Coilover kit
Both the know-how and technology from Porsche and Manthey's many years of experience in GT racing were incorporated into the development of the coilover suspension. On the front axle, a MacPherson construction in upside-down design is used. The shock absorber has a housing tube made of high-strength aluminum to reliably and durably perform its wheel guidance task even on the racetrack. The damping unit is 3-way adjustable, and the aluminum support bearings also allow easy adjustment of the camber values on the front axle. The independent compression stage adjustment in low and high speed is carried out on the external reservoir via the adjustment wheels, which can be operated without tools. The rebound damping can also be adjusted via an adjustment wheel at the lower end of the damper housing. If the vehicle has a standard front axle lift system, the function is fully retained. An aluminium shock absorber is used on the rear axle. The 4-way adjustable damper (compression and rebound, in low and high speed) can be adjusted directly on the damper housing via adjustment wheels that can be operated without tools. The basic setup of the high-end chassis components was determined in countless laps on international race tracks, but above all on the Nürburgring-Nordschleife, and meticulously tuned by the engineers from Porsche and Manthey.

Brake line set with steel sheathing provides even more direct pedal feedback and a faster response time. This component of the kit was also tested and co-developed by Manthey on the Nordschleife.

The downforce of the vehicle is increased by installing various components, including additional air guide elements in the area of the front wheels, flaps on the front apron and a new rear wing of carbon. Aerodiscs on the rear wheels, also made of carbon, reduce turbulence in the rear of the vehicle and further increase aerodynamic efficiency. To accommodate the higher aero load caused by the rear wing, the rigidity at the rear end has been massively increased. The rear wing itself is connected directly to the body with the help of special supports (in the GT3 RS without Manthey Performance Kit, the wing is attached to the rear lid). Among other things, the aerodynamics package was tested in the wind tunnel in Weissach, which remains one of the most modern of its kind: The blower with a diameter of eight metres has extremely lightweight carbon blades and can generate wind speeds of up to 300 km/h (186 mph) on the tested vehicle in the measurement area.

Porsche and Manthey combined their know how and technology from many years of experience in GT racing in the development of the threaded suspension. A McPherson upside-down design is used on the front axle. The spring strut features a high-strength aluminium housing tube to perform its wheel guidance function reliably and durably even in race track use. The damping unit is 3-way adjustable, and the aluminium support bearings also enable easy adjustment of the camber values on the front axle. The independent pressure stage adjustment in low and high speed is carried out on the external reservoir via the tool-free adjusting wheels.

The rebound stage can also be adjusted via an adjusting wheel on the lower end of the damper housing. If the vehicle has a standard front axle lift system, the function is retained in full. The rear axle features an aluminium spring strut. The four-way adjustable damper (compression and rebound, at low and high speed) can be adjusted via tool-free adjusting wheels directly on the damper housing. The basic setup of the high-end chassis components was determined in countless laps on international race tracks, but above all on the Nürburgring-Nordschleife, and meticulously tuned by the engineers at Porsche and Manthey

Fits 2018-2019 GT3 RS models. Brake pads, wheels, and decals are not included. Porsche only recommends installation in conjunction with Magnesium wheels (see link below if your car isn't already equipped). Depending on your installation, additional parts/hardware could be necessary at an additional cost. Special order from Germany, contact us for details.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
Warranty claims must be processed in person at an authorized Porsche Service Center
Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center
