Porsche 992 Turbo S Aero Rear Diffuser

The GW9 carbon fiber diffuser is purpose-built to improve aerodynamic balance and reduce rear lift and is a key component of our complete aerodynamic program for the Porsche 992 Turbo S. With its aggressive design and precision-engineered airflow channels, the diffuser helps manage airflow under the car for improved stability and performance at high speeds.

Made using the same aerospace-grade autoclave process as our Gunther Werks components, this diffuser provides industry-leading strength, stiffness and surface quality. Each unit is made from resin-pre-impregnated, vacuum-formed carbon fiber, resulting in a product that is 20-30% stiffer and more durable than standard wet-lay options.

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

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