What is a Porsche Manthey Kit?
Manthey Racing, a Porsche-owned motorsport specialist, develops high-performance kits to enhance the track capabilities of select Porsche models. These kits integrate aerodynamic enhancements, lightweight materials, and upgraded suspension components, all fine-tuned for superior performance. The result is improved downforce, optimized handling, and increased stability, ensuring Porsche owners can push their vehicles to the absolute limit on the track.
Manthey Kit for the 992 911 GT3 RS: A Downforce Revolution
One of the most notable features of the Manthey Kit for the Type 992 911 GT3 RS is its extensive aerodynamic modifications, which increase downforce without adding additional drag. The revised front lip, carbon fiber Gurney flaps, and dual dive planes improve airflow at the front axle. The rear window is replaced with a lightweight carbon fiber panel, reducing weight by 25% compared to glass.
Additional enhancements include a carbon fiber shark fin inspired by the Porsche brand’s 963 race car, which improves cornering stability. A split DRS rear wing with larger end plates and an expanded rear diffuser further refine aerodynamics. With these modifications, the 911 GT3 RS Manthey Kit produces over 2,200 lbs. of downforce at 177 mph, enabling drivers to maintain higher speeds through corners with greater confidence.
Semi-Active Coilover Suspension for Maximum Precision
The Manthey Kit’s semi-active coilover suspension adapts to the increased downforce. Front axle spring rates increase by 30%, while rear axle rates rise by 15%. Four-wheel and three-body acceleration sensors work with a newly developed control unit to adjust dampers automatically for optimal stability and responsiveness. The dampers feature independent rebound and compression adjustments, allowing drivers to fine-tune their settings based on driving conditions and personal preferences.
In Track mode, further manual adjustments can be made using the steering wheel dials, ensuring the most precise handling on different track surfaces.

Track-Optimized Brakes and Customization Options
For improved braking performance, the Manthey Kit includes braided steel brake lines, enhancing pedal feedback and delivering immediate response. Additionally, customers can personalize their GT3 RS with illuminated carbon fiber door sill guards featuring Manthey lettering, Neodyme decals, and a choice of red, black, or yellow towing eye.
Manthey Kit for the 991 911 GT2 RS: Ultimate Control and Stability
The Manthey Performance Kit for the Type 991 911 GT2 RS significantly improves aerodynamics and handling. A new front spoiler with additional flaps, carbon underbody elements, and optimized air guides enhance front-axle downforce. Rear downforce is increased from 205 lbs. to 440 lbs. at 124 mph with a redesigned rear spoiler, larger diffuser, and aerobics on the rear wheels. These changes improve high-speed cornering and straight-line stability.
Suspension and Braking Enhancements for the 911 GT2 RS
The 911 GT2 RS Manthey Kit also benefits from a track-optimized coilover suspension, with front shock absorbers adjustable in three settings and rear shock absorbers with four settings. Steel-encased brake lines provide more direct pedal feedback, ensuring precise braking control. Magnesium wheels, which save approximately 25 lbs., come in various finishes, including Brilliant Silver, Black, Aurum, White Gold Metallic, and Platinum.
An additional water tank increases the spray-cooling capacity for the intercoolers by 2.3 gallons, extending the time between refills and improving thermal management during high-performance driving.
