Manthey kits finally land on U.S. soil for Porsche.
Engineered on the racetrack with everyday road use in mind, Porsche’s lineup of GT cars offers a true race-inspired driving experience for customers looking to add some excitement to the garage. And while countless hours of design and testing go into producing what seem to be the ultimate sports cars, the team at Manthey Racing, a division of Porsche, takes things even further with aero, braking, and suspension upgrades for two of the most track-focused 911 variants. Today, Porsche and Manthey Racing proudly announce that kits will now be offered in the U.S. for the 992 911 GT3 RS and 991 911 GT2 RS.

The Manthey Kit for the 992 911 GT3 RS transforms it into a downforce powerhouse, generating over 2,200 pounds at 177 mph. Upgraded aerodynamics include a larger front lip, shark fin, and split DRS rear wing, while lightweight carbon fiber parts replace heavier components. The semi-active coilover suspension is fine-tuned to handle the increased downforce, offering precision adjustments for any track. Brake upgrades guarantee a sharper response in the corners, while personalization options like carbon fiber accents and custom decals let owners add their own touch.

For the 991 911 GT2 RS, the Manthey Kit delivers precise upgrades, including aerodynamic tweaks that significantly increase downforce and improve high-speed stability. Magnesium wheels shed weight and maintain strength, and a larger water tank for intercooler spray cooling keeps the car running efficiently during intense track sessions. The track-optimized suspension allows for customizable handling, and steel-lined brake lines improve braking feedback. These improvements make the GT2 RS even more exciting to drive, with balanced performance that lets drivers push the limits confidently.
Both kits are available to order immediately through Manthey-certified U.S. Porsche dealerships with delivery expected by Spring, 2025. MSRP for the 911 GT3 RS Manthey Kit is $116,160. MSRP for the 911 GT2 RS Manthey Kit is $113,140. Both prices exclude taxes and dealer installation costs.
