Manthey will be contesting the 2026 IMSA Michelin Endurance Cup with a strong driver line-up. 

Hardly any other production car is used by its customers as often at track days as the Porsche 911 GT3. With the new Manthey Kit, the performance of the high-performance sports car on the track can now be increased even fur-ther - through extensively revised, particularly efficient aerodynamics with significantly increased downforce, a modified chassis and optimised brake components. 

Manthey successfully defends the FIA Endurance Trophy for LMGT3 teams and drivers with Ryan Hardwick (USA), Riccardo Pera (Italy), and Richard Lietz (Austria) in the Manthey 1st Phorm Porsche.

After the double championship victory in the series debut in the 2024/25 Asian Le Mans Series (ALMS), Manthey is continuing its involvement in the 2025/26 season and will once again field two Porsche 911 GT3 R in the endurance races across Asia.

Manthey is set to expand its GT3 racing programme to the North American IMSA WeatherTech SportsCar Championship for the first time in 2026. The team based close to the Nürburgring will enter one Porsche 911 GT3 R in both the GTD and GTD PRO classes of the five IMSA Michelin Endurance Cup races.
