Porsche 911 GT3 RS Gets Carbon Fiber Shark Fin Window With New Manthey Kit
A weight savings feature that when paired with other updates provides 2,200 pounds of downforce at speeds of 177 mph.
Porsche has introduced the Manthey Kit for the 911 GT3 RS (992), designed to enhance its track performance even further. Developed in collaboration with Manthey Racing, the kit focuses on improved aerodynamics, upgraded suspension, and optimized braking components for maximum stability and speed on the racetrack.
Key aerodynamic upgrades include a larger carbon fiber front spoiler lip, redesigned wheel arch Gurney flaps and two dive planes on each side of the front bumper. At the rear, a lightweight carbon fiber window integrates a shark fin for improved cornering stability, while a wider rear diffuser and split carbon fiber DRS wing increase downforce without additional drag. These modifications enable the car to produce over 2,200 pounds of downforce at approximately 177 mph.
The semi-active coilover suspension has been tuned for higher downforce, with spring rates increased by 30 percent at the front and 15 percent at the rear. Advanced sensors and a new control unit ensure precise damper adjustments based on driving conditions. Track mode allows for manual adjustments via rotary controls on the steering wheel.
Brake upgrades include steel-sheathed lines for a more responsive pedal feel and optional racing brake pads tailored for the Porsche Ceramic Composite Brake system. These pads improve performance consistency, reduce fading and enhance durability under demanding track conditions.
Customers can personalize their vehicles with illuminated carbon fiber door sills, decals and towing eyes in various colors. The Manthey Kit is available for order now, with EU deliveries beginning in January 2025 and international availability starting March 2025.
