Very few production cars see as much regular track use from their owners as the Porsche 911 GT3. With the Manthey Kit, Porsche offers a package of performance upgrades that go well beyond the Weissach Package, aimed squarely at drivers who are serious about track performance.

The kit brings heavily revised aerodynamics that deliver substantially more downforce, along with reworked suspension settings and improved brake components. Together, these changes sharpen the car’s circuit capability.

With the Manthey Kit fitted, the 911 GT3 recorded a 6:52.981 lap of the Nürburgring Nordschleife — roughly 2.8 seconds quicker than the previous Manthey-equipped version.

The aerodynamics of the 911 GT3, which are already designed for high downforce as standard, have been further optimised for track use.

The front lip has been redesigned and extended forward by 12 millimetres. Special front diffusor fins in the front underbody and flaps attached to the sides of the vehicle increase downforce at the front axle.

The carbon-fibre wheel covers (aerodiscs) at the rear reduce drag, completing the interaction of all the car’s aerodynamic components to optimise airflow and maximise overall efficiency.

Together with Manthey, Porsche has developed a special four-way coilover suspension for the 911 GT3 that can be adapted for circuit use.

Lightweight 20- and 21-inch forged wheels are available as an option for the Porsche 911 GT3. These reduce the unsprung mass by a total of six kg compared to the standard wheels.
