Motorsport technology for maximum performance on the racetrack
Porsche offers a Manthey kit for the current 911 GT3 RS (992) that further enhances racetrack performance. The kit provides significantly more downforce and therefore higher cornering speeds. The suspension has been specially adapted for use on the racetrack, while the brakes have been optimised for the particularly high demands of trackdays. The new Manthey kit was developed in close cooperation between the Porsche Development Centre in Weissach and the Manthey engineers in Meuspath. The race track-oriented components are sold through 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 recognisable. The spoiler lip with its new profile has been significantly enlarged and stabilised with reinforcing elements made of carbon fibre. Together with newly designed Gurney flaps on the wheel arches and two so-called “dive planes” on each side of the front bumper, the spoiler lip ensures increased downforce on the front axle. The rear windscreen is replaced by a 25 per cent lighter carbon panel, on which a carbon fin is mounted. This fin, derived from the victorious 963 from the World Endurance Championship, increases stability in bends. In combination with six additional roof fins, it directs the warm exhaust air from the front radiator to the outside, ensuring that cool air reaches the rear unhindered – 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 wider rear diffuser with longer carbon fibre fins also increases downforce without increasing drag. The carbon aerodynamic wheel covers (“Aerodisc”) further reduce drag and are an ideal complement to the aerodynamic components, which work together seamlessly to optimise airflow and maximise efficiency. Overall, downforce has been significantly increased without increasing drag. At 285 km/h, the 911 GT3 RS with Manthey kit generates more than 1,000 kg of downforce. This enables higher speeds in fast and medium-fast bends and maximises vehicle stability.
Semi-active coilover suspension
The spring rates of the semi-active coilover suspension have been adapted to the higher downforce values. The spring rates have been increased by 30 per cent on the front axle and 15 per cent on the rear axle. Four wheel and three body acceleration sensors as well as a newly developed control unit ensure fully automatic damper control that works extremely quickly and precisely. The new shock absorbers have two separate valves for compression and rebound, which are controlled independently of each other. This ensures precise adaptation to changing driving situations and road conditions, which maximises stability on the racetrack. Depending on the driving mode (Normal, Sport, Track), different parameter sets are available for different basic characteristics of the dampers. In Track mode, the basic set-up can also be individually adjusted using the rotary controls on the steering wheel.
