Porsche is offering a Manthey Kit for the 911 GT3 RS (992) for even higher performance on track. The kit provides significantly increased contact pressure and, as a result, higher cornering speeds. The suspension has been specially adapted for driving on the racetrack, while the brakes are optimised for the particularly high demands of track-day driving. The new Manthey Kit was developed as part of a close collaboration between the Porsche Development Centre in Weissach and the Manthey engineers in Meuspath.

Improved downforce at high speeds

The extensive changes to the aerodynamic components make the Manthey Kit for the 911 GT3 RS immediately recognisable. The spoiler lip with its new wing profile has been significantly enlarged and is supported by reinforcing elements made of carbon fibre. Together 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-per-cent lighter carbon fibre panel on which a carbon fibre 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 fibre DRS wing element – in conjunction with larger, redesigned end plates – increases downforce on the rear axle. The significantly widened rear diffuser with longer carbon fibre fins also increases downforce without increasing air resistance. The carbon fibre ‘aerodisc’ wheel covers reduce air resistance and make the perfect addition to the combination of aerodynamic components, which work seamlessly to optimize air flow 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 per cent on the front axle and by 15 per cent 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 personal preferences using the rotary controls on the steering wheel.

Racing brake pads specially optimised 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 and reduce fading while also increasing responsiveness and control precision. The brake pads are characterised by consistent performance over a wide temperature range and very good wear resistance for both the pads themselves as well as the discs.

Individuality

Customers wishing to add more visual touches can customize their 911 GT3 RS with particularly sporty accessories. Illuminated door sill guards in carbon fibre with Manthey lettering in red and white, LED door projectors with white Manthey lettering, and decals in various colours on the carbon ‘aerodiscs’ emphasize the distinct character of the 911 GT3 RS. In addition, the Manthey lettering can be applied to the car doors in either Neodyme, white or black. A towing eye is available for when driving on the racetrack, and 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 be removed if the car is to be used on public roads.
