Manthey Porsche 911 GT3

The German company Manthey, which has long been behind Porsche's racing activities, has a solution for the well-off clientele who feel that (and) the redesigned 911 GT3 (992.2) can be even faster and sharper.

Manthey Racing has repeatedly proven that the "elfs" with the charismatic GT3 badge can be even faster without any necessary interventions under the rear cover where the legendary 4-liter 6-cylinder boxer engine "resides"; one of the last living atmospherics.

With the latest Performance package from Manthey (which will appeal to clientele willing to spend around 50,000 euros), the redesigned 911 GT3 (992.2) has come even closer to the GT3 racing version, as best shown by measurements on the legendary German Nürburgring Nordschleife track.

DTM champion Ayhancan Güven completed the 20.8-kilometer lap in 6 minutes and 52.981 seconds, 3 seconds faster than the result of Manthey's GT3 from the 992 Series before the redesign, and according to Manthey, this was all achieved in less than ideal track conditions. For comparison, the standard Porsche 911 GT3 (992.2), driven by factory driver Jörg Bergmeister, achieved a time of 6:56.294.

The key reason for the improved time is the sophisticated aerodynamics of the carbon body components (including the adjustable rear spoiler and diffuser from the GT3 RS model), which provide significantly more grip in corners, and the speed is also supported by the flat floor and the distinctive aero caps on the rear wheels.

1,190 pounds of downforce... In its standard factory configuration, the 911 GT3 already generates significant downforce. Manthey's new kit focuses on making the car even more track-focused. The entire underbody has been transformed into a continuous aerodynamic element. The airflow-directing fins under the car are much larger and now measure approximately 150 cm in length, representing a 99 cm increase compared to the standard vehicle design. This allows them to generate additional downforce in a particularly efficient manner. To achieve this result, the trunk floor of the production vehicle now has a cover that helps create a completely smooth underbody. The front spoiler has been redesigned and extended by almost 1.3 cm. Special diffuser fins on the lower front and flaps attached to the sides of the vehicle increase downforce on the front axle. The 911 GT3's wing with swan-neck struts is wider and now features a Gurney flap. Larger side plates are noticeably curved inwards to achieve optimal airflow. The rear diffuser features longer fins and increases downforce without adding drag.

The carbon fiber aerodiscs at the rear reduce drag, completing the interaction of all the car's aerodynamic components to optimize airflow and maximize efficiency. Overall, downforce increases considerably, while drag remains the same. Even in the least aggressive configuration, the car equipped with the kit generates 355 kg of downforce. In the most extreme configuration, intended exclusively for track use, this value rises to 540 kg at the same speed.

Adjustable coilover suspension...In partnership with Manthey, Porsche developed a special four-way coilover suspension for the 911 GT3, which can be configured for track use. The shock absorbers have four levels of adjustment, allowing for changes in compression and rebound without the need for tools. The spring rate on the front axle is increased by 10% compared to the previous model's Manthey kit to compensate for the increased downforce. This contributes to improved handling in sporty driving. The track-focused suspension increases mechanical grip and makes the car even more stable, especially when going over kerbs.

Behind the ultra-light wheels is a multi-adjustable aluminum suspension that is optimized for use on the track, and an important part of the Performance Package is the brake pads used on racing "elfers". At the Manthey (Meuspath) headquarters, they emphasize that all the components that require a considerable amount of money do not affect the Porsche factory warranty.

Lightweight 20- and 21-inch forged wheels are available as an option for the Porsche 911 GT3. They reduce unsprung mass by a total of 6 kg (13.2 lbs) compared to the standard wheels. They are available in Brilliant Silver, Neodyme, and Black (satin gloss). Braided steel brake hoses are included as standard in the kit. This ensures precise pressure and optimized braking control.

Those wishing to add even more visual detail can personalize their 911 GT3 with specially designed sporty accessories. Carbon fiber door sills with illuminated "Manthey" lettering, LED door spotlights with white "Manthey" lettering, and the option to apply "Manthey" lettering to the doors are ways to emphasize the bold character of the 911 GT3. In addition, the carbon fiber aero discs, included in the kit, are available with a variety of colored decals. Tow straps in red, black, or yellow are also available and can be attached to the threaded holes in the front and rear bumpers, although they must be removed before driving on public roads. The 911 GT3 can also be enhanced with carbon fiber front air vents and rear air intakes.

At the Nürburgring Nordschleife circuit, used by Porsche as a test track for the development of sports cars, the 911 GT3 with the Manthey Kit was able to show its full potential. With the current DTM champion, Ayhancan Güven, at the wheel, and in less than ideal conditions, the modified GT completed a lap of the 20.8 km circuit in the Eifel region in 6:52.981 minutes – 2.76 seconds faster than the previous generation (992.1) of the 911 GT3 with the Manthey Kit. Both cars were equipped with Michelin Pilot Sport Cup 2 R tires, available as an option. The lap time was certified by a notary present at the site.
