The Rear Diffuser is designed to fit the AMG GT63 (S).

  • What exactly is prepreg carbon fiber?
  • Prepreg is widely known as the finest process in carbon fiber manufacturing and has been used for aerospace and military applications because of its superior consistency in weight, thickness, fitment, resin, carbon layout, and overall quality.
  • The pre-impregnated (prepreg) fiber method creates stiffer, stronger laminates with controllable, predictable results and the result is a consistent, tight fiber weave which not only looks amazing, but adds strength. Other companies use a lower cost, wet-layup method which results in components of inferior, strength, appearance and overall quality.




RENNtech Carbon Fiber Quality Control

RENNtech strives to deliver the highest quality carbon fiber products in the industry. All of our designs are unique and fully developed in house by our skilled engineers and designers. These products can be very complex and are handcrafted utilizing the pre-preg manufacturing process, making each product truly unique. Therefore, a few minor inconsistencies and differences between parts is possible. Whether it’s a small deviation in the weave layup or slight inconsistency in the finish, this is completely normal in carbon fiber manufacturing because of the nature of the material and production process. Any parts with more noticeable areas of concern are scraped entirely and never offered to our highly discerning clientele. Comparing to alternative product, we're confident you will be more than satisfied with our authentic RENNtech carbon fiber components.
