Porsche 911 GT3 with Manthey Kit (2026) — a reinforced racing version with the same power unit The Porsche 911 GT3 with Manthey Kit (2026) is a road version of the new generation 911 GT3 (992.2), equipped with a certified upgrade package from Manthey, developed in collaboration with Porsche.
The package retains the factory power output but significantly improves aerodynamics, chassis, and handling, turning the GT3 into a car that is as close to a track car as possible.
The power unit is still based on the naturally aspirated 4.0-liter flat-six engine characteristic of the latest generation GT3. There is no increase in power—power remains at the factory level.
Traction is delivered via a 6-speed manual transmission or a 7-speed PDK robotic transmission (depending on the configuration), with rear-wheel drive (RWD).
Acceleration to 100 km/h takes about 3.4 seconds (factory GT3).
With the Manthey package, the main changes are to the aerodynamics and chassis: a modified underbody, extended flanges, and lightweight parts.
For example, the package generates downforce of up to ≈ 540 kg in race mode without increasing air resistance.
The maximum speed with the factory transmission is around 318-330 km/h, depending on the configuration.
The body is equipped with active aerodynamics, an improved suspension with four-mode adjustment, lightweight body panels, and specially adapted brakes.
The interior is driver-oriented: minimalist sports seats, a racing-style steering wheel, a digital instrument panel, and an emphasis on track functionality.
