RENNtech | C190 | AMG GT R | Rear Diffuser Extensions | Carbon Fiber

These RENNtech rear diffuser extensions create an all new aggressive and functional aesthetic for the rear of the C190 - AMG GT R.  The design and engineering teams at RENNtech HQ spent countless hours fine tuning the part to perfectly compliment the AMG GT R exterior while improving the underbody airflow.  Each side is constructed from 100% pre-preg carbon fiber that make up the diffuser improvments. The diffuser extensions are desinged to achieve the best possible aerodynamic result in combination with the RENNtech Aro Package for the AMG GT R. The full package of aero parts for the AMG GT R includes Front Canards, Sider Rocker Panels, Diffuser Attachments and Rear Lipp Attachment.

The diffuser assembly also features a unique acrylic coating process which protects the carbon fiber from any harmful UV and humidity degradation.  This acrylic coating is applied inside and out to ensure full coverage and protection, unlike any other coating process.  Once the acrylic coating is cured, the part is then covered using a high end automotive clear coat to create a beautiful gloss finish.

This diffuser is designed to fit the C190 - AMG GT and GT S Model year 2015 and up. Modifications to the OEM rear bumper are NOT necessary, installs with 3M double-sided automotive tape (included).

• 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.
• To explain this process in short, the fiber is pre-impregnated (hence the name) with resin at a production facility, rolled on spools, and frozen to prevent the resin from curing prematurely. This material is than cut and hand laid into a mold to the proper thickness and cured at strictly controlled temperatures. This process creates a laminate with a precisely controlled resin volume and in turn is 20-30% stiffer and stronger than an equivalent thickness wet laminate process.
• This ensures our customers receive components which not only look good on the vehicle standing still, but won’t crack, warp, fall off or fade when mounted to the exterior of their vehicle after six months or while driving at high speed

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.
