Manthey Kit for Porsche 911 GT3 RS (992)

The kit significantly increases contact pressure and, as a result, higher cornering speeds. The suspension has been specially adapted for driving on the racetrack, while the brakes are optimized for the exceptionally high demands of track-day driving. The new Manthey Kit was developed in close collaboration between the Porsche Development Centre in Weissach and the Manthey engineers in Meuspath. These track-focused components will be distributed via Porsche Centres.

More than a tonne of downforce at 285 km/h
The extensive changes to the aerodynamic components make the Manthey Kit for the 911 GT3 RS immediately recognizable. The spoiler lip, with its new wing profile, has been significantly enlarged and supported by carbon fiber reinforcing elements. With redesigned wheel arch Gurney flaps and two dive planes on each side of the front bumper, the spoiler lip increases downforce on the front axle. The rear window is replaced by a 25-percent lighter carbon fiber panel on which a carbon fiber shark fin is mounted.

The fin was derived from the World Sportscar Championship-winning 963 and is designed to increase cornering stability. In conjunction with six additional roof fins, it also diverts the warm output air from the front radiator outwards, thus ensuring that cooler intake air is drawn in at the rear, even under extreme operating conditions. The split carbon fiber DRS wing element - in conjunction with larger, redesigned end plates - increases downforce on the rear axle. The significantly widened rear diffuser with longer carbon fiber fins increases downforce without increasing air resistance.

The carbon fiber "aerodisc" wheel covers reduce air resistance and make the perfect addition to the combination of aerodynamic components, which work seamlessly to optimize airflow and maximize overall efficiency. Overall, the downforce has been increased significantly without increasing drag. At 285 km/h, the 911 GT3 RS with Manthey Kit produces more than 1,000 kg of downforce. This enables higher speeds on fast and medium-speed corners and maximizes vehicle stability.

Semi-active coilover suspension
The spring rates of the semi-active coilover suspension have been adjusted for the higher downforce figures. The spring rates were increased by 30 percent on the front axle and by 15 percent on the rear. Four wheel- and three body-acceleration sensors - along with a newly developed control unit - ensure fully automatic damper tuning that is extremely fast and even more precise than before. The new shock absorbers operate with two separate valves for the compression and rebound stages and are independently controlled.

This ensures precise adjustment for changing driving situations and road conditions, which maximizes stability on the racetrack. Depending on the driving mode (Normal, Sport, Track), different sets of parameters are available for different basic damper characteristics. In Track mode, the basic setup can also be manually adjusted to your preferences using the steering wheel's rotary controls.

Racing brake pads are specially optimized for track days.
The braking components of the Manthey Kit are tailored to the requirements of driving on the racetrack. The steel-sheathed brake lines provide an even more direct pedal feel and a faster response time. Optional racing brake pads are available for cars with the Porsche Ceramic Composite Brake (PCCB). These pads have been specially developed for track-day use to reduce fading while also increasing responsiveness and control precision. The brake pads are characterized by consistent performance over a wide temperature range and very good wear resistance for both the pads themselves and the discs.

Extensive accessories enhance individuality.
Customers wishing to add more visual touches can customize their 911 GT3 RS with particularly sporty accessories. Illuminated carbon fiber door sill guards with Manthey lettering in red and white, LED door projectors with white Manthey lettering, and decals in various colors on the carbon "aerodiscs" emphasize the 911 GT3 RS's distinct character. In addition, the Manthey lettering can be applied to the car doors in either Neodyme, white, or black.

A towing eye is available for driving on the racetrack. It can be used on the front or rear. It is available in red, black, or yellow and can be attached to either end using the appropriate threaded hole. It must, however, be removed if the car is to be used on public roads.

The cost?
The Manthey Kit for the 911 GT3 RS can be ordered now. It will be available in EU markets from January 2025 and outside the EU from March 2025. The pricing starts from 76,911 euros, excluding country-specific VAT and installation at a Porsche Centre. The really good thing is that the manufacturer's warranty for the Porsche 911 GT3 RS remains unaffected.
