Purpose-built to enhance aerodynamic balance and reduce rear-end lift, the GW9 Carbon Fiber Rear Diffuser is a key component in our complete aero program for the Porsche 992 Turbo S. With its aggressive design and precision-engineered airflow channels, the diffuser helps manage underbody airflow for improved stability and high-speed performance.

Produced using the same aerospace-grade autoclave process as our Gunther Werks components, this diffuser delivers industry-leading strength, rigidity, and surface quality. Each unit is crafted from resin pre-impregnated, vacuum-formed carbon fiber, resulting in a product that’s 20%–30% stiffer and more durable than standard wet lay-up alternatives.

Our vacuum-forming technique removes excess resin, minimizing weight while maintaining structural integrity. This meticulous process allows for tighter fitment tolerances and a refined finish that integrates perfectly with factory body lines and mounting points.

Constructed with a blend of unidirectional and 2x2 twill weave carbon fiber, the GW9 rear diffuser represents the intersection of performance engineering and lightweight artistry.

Vorsteiner Technology

Not “Good Enough.” Engineered to Lead.

At Vorsteiner, “good enough” isn’t part of our vocabulary. Every aerodynamic component is engineered to push boundaries-not follow them. Using a state-of-the-art aerospace-grade autoclave process, our carbon fiber parts deliver exceptional rigidity, structural integrity, and surface finish.

The result? Aerodynamics that don’t just look advanced-they are advanced.

OEM Fitment

Factory Precision. Elevated Design.

Our proprietary manufacturing process allows for exceptional control over tolerances, fit, and finish. Each Vorsteiner component is engineered to align precisely with factory shut lines and body contours—delivering an installation experience that feels OEM, but looks unmistakably premium.

This isn’t “close enough” aftermarket fitment. This is carbon fiber that installs cleanly, fits perfectly, and elevates the vehicle’s design language.

Stronger and Lighter

Less weight. More strength. Zero compromise.

Vorsteiner components are manufactured using resin pre-impregnated, vacuum-formed carbon fiber—technology reserved for high-performance aerospace and motorsports applications. Compared to traditional wet-lay carbon fiber, this process produces parts that are 20–30% stiffer and stronger while eliminating unnecessary weight.

By vacuum-drawing excess resin during curing, we remove what doesn’t contribute to strength—resulting in lighter components without sacrificing rigidity or durability.
