Recently, Porsche announced the price of two high-performance kits for the 911 GT3. Among them, the official guided price of the 911 GT3 Manthey high-performance kit is 558,000 yuan, which is suitable for 911 GT3 models; the official guided price of the 911 GT3 Manthey suspension kit is 169,800 yuan, which is suitable for 911 GT3 and 911 GT3 travel models. The test drive with this high-performance suite will be held for the first time for the Chinese public at the Porsche Experience Center in Shanghai on September 13, 2026, Porsche Enjoy Sports Car Day. The Porsche 911 GT3, equipped with the Manthey high-performance kit, set a lap time of 6 minutes 52.981 seconds on the Nürburgring North Circuit, 2.76 seconds shorter than its predecessor. For those who buy the new 911 GT3, Porsche retrofitted the Manthey performance kit prior to delivery for a one-step, factory-tracked configuration. The 911 GT3 performance kit covers the complete upgrade from aerodynamics, suspension system to brake system, including adjustable crown dampers, carbon fiber aerodynamic rims, steel braided brake lines, front lips and flaps, front diffuser fins, elongated body bottom fins, front undercover plates, rear diffuser plates with carbon fiber fins, and carbon fiber spoilers. The Manthey high-performance kit brings a significant performance upgrade to the 911 GT3, with an aerodynamic design that is almost rebuilt. The entire body bottom is built as a continuous pneumatic component, with the underbody deflector extended to 1.5 meters, with the front lip extending 12mm forward, the swan neck spoiler and the Gurney flaps. At a speed of 285 km/h, up to 540 kg of downforce can be generated in the track mode, and up to 355 kg in the road mode, while the wind resistance remains unchanged to achieve a higher overturning speed. The rear diffuser uses extended bottom fins to increase the downforce without increasing the wind resistance. The rear carbon fiber aerodynamic rim cover reduces wind resistance and improves synergy between aerodynamic components throughout the vehicle. The kit is equipped with a four-way adjustable wring shock absorber, which is suitable for different track occasions. Suspension struts support four-way adjustment to adjust the rebound and compression damping of the shock absorber without the use of tools. The front axle spring coefficient is increased by 20% compared to the previous model equipped with the Manthey high-performance kit, matching the greatly increased downforce, which helps to increase the maneuverability under extreme conditions. Optimized track suspension increases mechanical grip and makes the vehicle more stable, especially when pressing over the curb. The lightweight forged rims reduce the non-spring load mass by a total of 6kg, with steel braided brake lines and optional ceramic compound brake system (PCCB) racing brake pads for precise braking foot feel and long-lasting thermal attenuation resistance. The wheels are available in bright silver, metallic neodymium, and black. In addition, the owner can enhance the personalized performance of the vehicle with a variety of highly sporty accessories in addition to the optional standard parts. For example: the Manthey decal set highlights the sharp personality of the 911 GT3; the 20/21 "911 GT3 lightweight rim set with central locking provides weight loss for the body; the front/rear trailer ring for the track, available in red, black or yellow, can be installed in the designated threaded holes in the front/rear of the vehicle; the carbon fiber set includes the carbon fiber air outlet on the front luggage compartment cover and the rear air inlet. For those who already own a 911 GT3, there is an option to modify the Manthey suspension kit, which contains a four-way adjustable cuff shock absorber kit, with the suspension post supporting four-way adjustment. The front axle spring coefficient is increased by 20% compared to the previous model equipped with the Manthey high-performance kit, which improves maneuverability under extreme conditions.
