Built for drivers who crave lap-time precision, the latest Manthey Kit for the current 911 GT3 (992.2) brings track-focused engineering straight from Weissach and Meuspath. Developed jointly by the Porsche brand’s development team and Manthey racing engineers, the kit delivers higher cornering potential while keeping the factory warranty intact when installed at Manthey-certified Porsche Centers.   

First, aerodynamics takes a major leap forward. The underbody has been reworked into a continuous aero surface, paired with dramatically longer turning vanes measuring about 59 inches. As a result, airflow underneath the car works harder and more efficiently. A redesigned front lip, added diffuser fins, and side flaps boost front-axle grip. At the rear, a wider swan-neck wing with a Gurney flap and curved end plates improves airflow control, while a revised diffuser adds downforce without extra drag. Carbon fiber aerodiscs complete the setup. Even in mild settings, downforce reaches 782 lbs., while the most aggressive track-only configuration pushes it up to 1,190 lbs.

Next, suspension and braking upgrades support the added aero load. A new four-way adjustable coilover suspension allows tool-free tuning of rebound and compression. Higher front spring rates improve stability, especially over curbs. Lightweight forged wheels cut unsprung weight by over 13 lbs., while braided steel brake lines deliver a consistent pedal feel during demanding track sessions.  

Finally, visual accessories add motorsport flair, from illuminated Manthey door sills to carbon fiber air outlets. Altogether, these upgrades clearly answer what’s new in the Manthey Kit for the Porsche 911 GT3? More grip, sharper control, and serious track intent.
