The Manthey Racing Forged Wheel Set for the 991 Porsche 911 GT3 is built with the same mindset that fuels Porsche’s factory-backed racing efforts. Every detail of these wheels is engineered for drivers who expect performance gains without sacrificing reliability or design. Designed to enhance every aspect of the 911 GT3’s handling and character, these forged monoblock wheels deliver a blend of durability, precision, and lightweight efficiency. Available now through Bulletproof Automotive, the wheels are tailored specifically for the 991.1 and 991.2 GT3 platforms.
At the heart of the Manthey Racing Forged Wheel Set lies its unison monoblock construction. Each wheel is crafted as a single unit rather than a multi-piece design, resulting in superior strength and rigidity. This process not only improves the overall durability but also ensures the wheels can endure the extreme demands of both racing environments and high-intensity track days. For owners who value resilience under pressure, the structural integrity of this monoblock formation provides confidence on every lap.
Manthey Racing developed this wheel set to meet the requirements of professional motorsport. The construction allows for consistent performance when subjected to high stress and heavy cornering loads. The design is rooted in efficiency, giving GT3 owners the advantage of competition-proven engineering that translates directly to the road.
While strength was a core goal, Manthey Racing prioritized weight reduction to unlock sharper performance. Compared to stock wheels, this set sheds approximately 7.9 kilograms. The reduction in rotating mass improves acceleration, braking efficiency, and steering feedback, making the car more responsive in every situation.
Less unsprung weight also means the suspension can react faster to surface changes, enhancing grip and ride quality. The benefit is felt immediately behind the wheel, where the 911 GT3’s naturally aspirated flat-six and precision chassis feel even more alive.
Manthey Racing offers the forged wheel set in a variety of finishes, allowing owners to match their GT3’s presence with subtle elegance or bold contrast. Choices include Brilliant Silver, Gold, Matte Platinum Silver, and Matte Satin Black. Each finish highlights the wheels’ intricate details while maintaining durability for long-term use.
Whether paired with Porsche’s signature paint colors or custom liveries, these finishes ensure the wheels not only perform at the highest level but also complement the GT3’s unmistakable design.
Designed exclusively for the Porsche 911 GT3 (991.1 and 991.2), the Manthey Racing forged wheel set fits seamlessly with factory bodywork and suspension geometry. Sizes are 20×9 inches for the front with a 52mm offset, and 20×12 inches for the rear with a 47mm offset. The set includes four wheels total, ensuring a balanced package optimized for the GT3’s chassis.
This precise sizing delivers an aggressive yet functional stance while accommodating the performance tires needed for both road and track driving.
