The Porsche 911 GT3 with the Manthey kit is 4 sec faster on the Nürb’

Manthey is perhaps best known for its competition Porsches – and it is indeed one of the first manufacturers of race cars based on Porsche products – but it also works on legal vehicles from Stuttgart.

The latest upgrade for a road-going Porsche comes in the form of the Manthey Performance Kit for the current-gen 911 GT3, and the results are impressive.

This is much more than just an aftermarket tuning kit, as it was developed in close cooperation between Porsche engineers and Nordschleife specialists from Manthey to Meuspath. The kit is sold through the Porsche dealer network and aims to make the car faster on the circuit. When equipped with this kit, the 911 GT3 laps the Nürburgring in 6:55.737 minutes, exactly 4.19 seconds faster than a production 911 GT3. wow!

The aerodynamic modifications are among the most recognizable. There is a large spoiler at the front and additional side blades installed on the front bumper. The underbody of the car has been modified with new elements to guide the air, which increase downforce on the front axle, a much appreciated improvement when cornering. At the rear, the spoiler is larger and the bumper diffuser gets extended CFRP fins. The carbon aero discs fitted to the rear wheels are a very special improvement.

Porsche has teamed up with Manthey to develop a four-way coil suspension that can be adapted for road or track use. The manufacturer promises to improve the « road holding on the limits » without sacrificing day-to-day usability. The 911 GT3 is fitted with 20-inch front and 21-inch rear alloy wheels. Lightweight forged wheels, which reduce the unsprung mass by 7.3 kilograms, are available as an option. The massive wheels hide special brake pads for racing, which are also available as an option.

Porsche and Manthey tested the modified 911 GT3 on the Nürburgring with Porsche test driver Kevin Estre at the wheel. As we mentioned above, the car covered the 20.6 kilometers of the most demanding circuit in the world in 4.19 seconds less than a production 911 GT3. The track-tested kit is already available to customers in Europe, with deliveries expected to begin this fall. Porsche promises that other markets will follow.
