Ahead of the much-anticipated reveal of the updated Porsche 911 GT3 RS, Manthey Racing, a German auto racing team, has introduced a factory-approved aerodynamic upgrade kit for the outgoing model. Backed by Porsche, which owns a 51% stake in Manthey, the package offers significant performance enhancements while maintaining the vehicle’s warranty.

The most noticeable change is the replacement of the rear window with a lightweight carbon fibre panel, which is 25% lighter than the original. The new panel integrates a shark fin antenna, inspired by the Porsche 963 endurance racer, and works in tandem with six smaller fins mounted on the roof. These fins direct hot air from the front radiators away from the rear intakes, allowing for cooler and more efficient airflow.

In the rear, the 911 GT3 RS is equipped with a redesigned carbon rear wing featuring modified endplates to boost downforce. A larger diffuser enhances stability, while carbon fibre aerodisc wheel covers reduce air resistance. These combined modifications enable the car to generate over 1,000kg of downforce at speeds of 284km/h.

Beyond its aerodynamic tweaks, the Manthey kit also includes mechanical upgrades. The front axle receives a 30% increase in spring rates, while the rear benefits from a 15% improvement. Additional components include new shock absorbers and racing brake pads, specifically designed for models equipped with ceramic-composite brakes. The package also features aesthetic touches such as carbon fiber decals, illuminated door sill guards, LED door projectors, and a towing eye for track use only.

Manthey’s engineers spent two years developing the kit, subjecting it to extensive testing across European racetracks. The company has hinted at plans to showcase its performance with a timed lap at the Nürburgring. The goal is to improve upon the stock GT3 RS’s lap time of 6 minutes and 49.32 seconds, set in October 2022, and approach the 6:43.30 record achieved by a previous-generation GT2 RS fitted with Manthey components in 2021.

For GT3 RS owners eager to upgrade, the new kit is already available for order. It will be delivered to European Union markets starting in January 2025, with availability in non-EU regions following in March. The price for this specific kit has not been disclosed.

With this latest offering, Manthey reaffirms its commitment to pushing the boundaries of Porsche’s engineering excellence, ensuring that the 911 GT3 RS remains at the forefront of track performance.
