Manthey Performance Aerokit. Porsche 991.2 GT2 RS ❭ 991044805
- Porsche 991.2 GT2 RS 3.8L PDK (700 bhp) 2018-19

Fits:
Porsche 991.2 GT2 RS - 2017 Onwards
The Manthey Kit for the 991.2 GT2 RS was developed in close collaboration between the Porsche Development Centre in Weissach and Manthey-Racing GmbH. Thanks to coordinated suspension, aerodynamics and braking components and the lightweight GT2 RS magnesium wheels, the breathtaking performance of the 991 GT2 RS has been tuned even more precisely to the demands of trackdays and tourist drives.
Porsche set a new course record at the Nürburgring in the sports car category in June 2021 with a 911 GT2 RS equipped with a Manthey Kit: The road-approved speedster completed a lap [sic] of the 20.8 km Nordschleife in just 6:43.300 minutes.
Aerodynamics package
Porsche and Manthey combined their respective technologies and know-how in the development of the aerodynamics package. In addition, individual components were developed with an eye to the defined performance targets. For instance, downforce at the front has been increased from 49 kg to 70 kg at a speed of 200 km/h through the use of a carbon underbody, additional air baffle elements in the area of the front wheels and flics on the front apron. The downforce at the rear end is increased from 93 kg to 200 kg at 200 km/h thanks to the rear wing in combination with the rear diffuser and aerodiscs, all of which are manufactured in carbon, further enhancing driving stability. The aerodiscs on the rear wheels reduce turbulence at the rear and have a positive effect on 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 attached directly to the body by means of special supports (standard: wing attached to the rear lid). The aerodynamics package achieves a shift in the aero balance and a 70% increase in overall downforce.
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 on the tested vehicle in the measurement area.
