The 992 Porsche 911 GT3 is already a benchmark for naturally aspirated performance, but Manthey Racing has built a reputation for showing that even perfection can be improved. Their Manthey Kit for the 992 Porsche 911 GT3 introduces a set of carefully engineered upgrades designed to sharpen handling, improve braking consistency, and generate greater aerodynamic stability. This package transforms Porsche’s flagship track car into an even more capable machine, blending factory-level development with racing expertise. Available now at Bulletproof Automotive, the Manthey Kit represents the most complete performance solution for GT3 owners who demand more.
At the core of the Manthey Kit is a fully reworked suspension system. The coilover kit allows precise tuning for ride height, damping, and rebound. On the track, this adjustability means a GT3 owner can optimize the car for different circuits or driving conditions. The suspension is engineered for a balance between compliance on the road and precision on the circuit, so the car feels stable at high speed without becoming harsh in everyday driving. By reducing body roll and sharpening steering feedback, the 992 Porsche 911 GT3 gains an extra layer of precision that pays dividends in lap consistency.
Manthey Racing knows that fast laps are won just as much under braking as they are under acceleration. The kit includes upgraded front and rear brake pads that deliver a stronger bite and better thermal capacity. Combined with braided brake lines, which resist flex under pressure, the system maintains a firm and consistent pedal feel even after repeated hard stops. For drivers pushing the 992 Porsche 911 GT3 deep into braking zones, this confidence is invaluable. With brake fade minimized, lap after lap can be run with the same precision and control.
Downforce is one of the most powerful tools in Manthey Racing’s arsenal, and the Manthey Kit provides a comprehensive aerodynamic rework. At the front, a redesigned lip spoiler, air guide elements, and bumper canards improve airflow while reducing lift. These components direct more air to the brakes while stabilizing the nose of the car at speed.
At the rear, a carbon fiber wing is paired with a new diffuser to increase downforce and enhance stability. Together, these elements give the 992 Porsche 911 GT3 the kind of planted feel that inspires confidence through fast corners. The added stability allows drivers to brake later and carry more speed, translating directly into lower lap times without sacrificing the car’s signature balance.
For enthusiasts seeking every possible advantage, the Manthey Kit can also be ordered with an optional forged wheel set in 20×9.5 front and 21×12 rear sizing. These wheels are not only visually striking, but they also reduce unsprung weight compared to the factory setup. That weight savings improves responsiveness, making the steering feel sharper and the suspension more effective. The wheels are engineered to complement the aerodynamics of the kit while maintaining Porsche’s durability standards.
The full Manthey Kit for the 992 Porsche 911 GT3 includes the coilover suspension kit, upgraded brake pads, braided brake lines, front lip spoiler, bumper canards, air guide elements, carbon fiber rear wing, rear diffuser, and the optional forged wheel set. Every component has been designed to work together, ensuring that improvements in one area are matched by gains in another. This synergy is what separates Manthey Racing from other tuners; the package feels like a natural evolution of the GT3 rather than an aftermarket add-on.
Manthey Racing is no stranger to Porsche development. As the team responsible for managing Porsche’s factory GT racing programs since 2013, they have competed and won at the Nürburgring and across the World Endurance Championship. That same engineering knowledge is distilled into the Manthey Kit, giving 992 Porsche 911 GT3 owners access to parts developed with the same rigor as competition machinery.
This connection to motorsport is not just marketing; it ensures that the parts withstand extreme use while delivering measurable improvements. For owners who view their GT3 as more than a weekend cruiser, this kit represents the closest connection to Porsche’s racing program currently available for the road.
Bulletproof Automotive brings the Manthey Kit for the 992 Porsche 911 GT3 to enthusiasts who refuse to compromise on performance. While compatibility is currently limited to German-spec cars, the availability of this package through Bulletproof ensures proper support and access to genuine Manthey Racing components. For GT3 owners, it is an opportunity to elevate an already legendary car to a higher tier of capability.
