The UCW rear wing is a great addition to your 991 GT3 to significantly increase downforce at the rear, increase confidence on track, and reduce lap times.

Verus Engineering developed the UCW rear wing to bridge the gap between our swan neck high-efficiency rear wing and our 300mm V1X airfoil.  With the 250mm curved chord, the UCW makes more downforce than the high-efficiency rear wing and significantly more downforce than similarly sized competitor wings.

Utilizing state-of-the-art analysis software during the R&D process, we optimized the airfoil for performance for the given build volume which is derived from the V1X.  Further utilizing CFD, we ensured the rear wing sees adequate airflow while installed and performs well.

During the design process; we utilised in-house scan data. This results in a product that features a near OEM fit and finish.

The UCW wing is the perfect addition to the track goer who requires a large bump in rear downforce to balance out a significant front aero package.

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.

The Manthey Kit for the 991.2 GT3 RS was developed in close collaboration between the Porsche Development Centre in Weissach and Manthey-Racing GmbH. Thanks to coordinated suspension, aerodynamic and brake components, the breathtaking performance of the 911 GT3 RS has been tuned even more precisely to the demands of trackdays and tourist drives.

Put it another way: 6:54.340 minutes for the 20.8-kilometre Nürburgring-Nordschleife. In this impressive time, Porsche works driver Kévin Estre lapped the "Green Hell" in a GT3 RS with an identical kit in April 2021.

Aerodynamics package

The downforce of the vehicle is increased by installing various components, including additional air baffle 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 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.
