RENNtech A1 Carbon Fiber Aero -package is designed to increase the aerodynamic properties and complement the aggressive looks of the Mercedes-AMG GT63 4-door coupe.

Front Splitter:
RENNtech’s four piece front splitter flows seamlessly into the front apron and wrapping around the bumper. The front splitter is designed to improve vehicle aesthetics and increase front end down force while still maintaining the same approach angle as the OE front fascia. The splitter is easy to install and retains the OEM clearance for parking stops and steep driveways.

Canards (Dive Planes):
RENNtech’s Canards are designed to increase downforce while complementing RENNtech's Front Splitter and the overall design of the AMG GT63 front facia. 

Side Skirts: 
Carbon Fiber Side Skirts were designed to complement the RENNtech front splitter and rear diffuser. This side skirt kit includes 4 high quality pre-preg carbon fiber pieces: 2-piece skirts for the left and right side of vehicle. These unique and refined aerodynamic pieces integrate flawlessly with the original lines of the vehicle.

Our rear diffuser is designed to decrease drag and increase down force by improving the underbody airflow and its transition to ambient air. As with the front splitter, our rear diffuser is manufactured using the high quality prepreg carbon fiber and is a quick and easy install that requires no modifications to the AMG GT 4-Door's rear bumper or underbody.

Fixed Rear Wing: 
The Carbon Fiber Rear Wing for the Mercedes-Benz AMG GT63 4-Door Coupe is designed to improve rear end stability with an aggressive yet highly functional design. Available with low- or high-profile stanchions, the wing attaches to a fixed wing base.

  • Please Note: Vehicles without factory fixed rear wing will require MB OEM wing base and Spoiler Deactivation module. OEM Fixed Wing Base: OEM:
  • RENNtech Carbon Fiber Wing is available with tall or low style stanchions. Please let us know your preference at time of order. Low Bracket Profile SKU: or Tall Bracket Profile SKU:

  • 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.
