Exclusive! 2025 Porsche 911 GT3 RS MR details leaked ahead of debut

Manthey Racing is all set to reveal a massive upgrade package for the 911 GT3 RS. While it will be revealed officially on November 22, we have already got our hands on some juicy details about the all-new Porsche 911 GT3 RS MR.

First up, the Manthey Racing upgrades focus primarily on improving the car’s aerodynamics and handling. The kit includes a carbon fibre rear wing with two elements and a DRS function, large carbon end plates, a carbon shark fin, and additional roof fins. Even the rear window is replaced with a carbon panel.

The 911 GT3 RS MR aero package also features an extended front splitter with support struts, dual aero flicks on either side of the front bumper with air curtains, and optimized front and rear diffusers. The car also gets lightweight carbon fibre wheel covers for improved downforce.

Besides aero updates, the 911 GT3 RS MR is also equipped with semi-active suspension and high-performance brakes with braided brake lines. Other details include front and rear tow lugs, door sill trim and LED door projectors.

The Manthey Racing 911 GT3 RS MR is expected to use the same 4.0-liter flat-6 engine as the standard car. This unit puts out 525 hp and 342 lb-ft of torque and will be paired with a 7-speed PDK.
