Rear Spoilers / Aerofoil

Manthey Performance Aerokit. 



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.

Salter Aero Carbon Fibre Rear Ducktail Lip  

The Salter Aero Rear Duck Tail Lip is not only a functional gurney flap, but also directs air closer to the bottom of the rear wing for those with higher wing risers. 

Designed to work with our +2" RS Wing Risers but these also work great with the OEM setup. 

100% Carbon fiber construction.

Rear spoiler suitable for Porsche 911/991 built from 09/2011.
Suitable for all model/body variants, except convertible.

• Including mounting accessories if necessary

• The GT3 RS's retaining struts and engine compartment lock are not included in the scope of delivery. These must be obtained originally from Porsche.

• Rear spoiler is made from the innovative and high-quality material Fiberflex. The advantages of this new composite material: Extremely high flexibility combined with great stability, splinter resistance and non-flammability. Very high manufacturing quality and low weight even allow it to be used in professional racing. The characteristic black surface is characterized by good processing options and guarantees professional results. Products made from Fiberflex are ideal for repairs and other conversion work thanks to their excellent cutting and gluing properties.
• Uniform surface structure enables painting without major preparatory work (product is unpainted)

Please note: This is a special-order item, can take 8-12 weeks to be delivered and once ordered cannot be cancelled.

Dramatically improve rear-end grip at speed with our 300mm chord, swan neck rear wing. The wing and full aero kit were designed in CFD to greatly improve the vehicle's performance on and off the track.

The wing is a large driving force behind the improvement in downforce, coupled with the front splitter it transforms the GT3RS into a track weapon.

The rear wing was designed, iterated, and tested in CFD and a wind tunnel. All component mounting was designed off OEM scans and requires no permanent modification to the rear hatch of the vehicle.

The uprights are CNC machined from 6061-T6 aluminum and were FEA analyzed to ensure strength was kept high while weight was minimized.
