AutoTecknic was established in 2000 and has since become one of the largest manufacturers and distributors of carbon fiber parts and accessories for a wide variety of manufacturers. Autotecknic's dry carbon fiber competition rear center diffuser for the F90 M5. Designed to mount directly onto the lower factory mounting location for a simple and fast installation. The diffuser is made from carbon fiber and is designed for lightness, high durability, and precise fitment. Dry carbon fiber's name also comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed vacuum (autoclave) to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest quality version of carbon fiber products that are produced.

Developed using Computational Fluid Dynamics (CFD), the profile is optimized to manage airflow efficiently, balancing downforce and drag to enhance high-speed stability without hurting everyday drivability. Whether you’re carving back roads or simply want a more commanding front-end presence, this lip gets the job done. Why it belongs on your G90 M5: Pre-preg Carbon Fiber Construction – Lightweight, high-strength carbon fiber with a flawless high-gloss finish Factory-Accurate Fitment – 3D scanned for precise alignment with the OEM front bumper CFD-Refined Aerodynamics – Optimized to improve stability by balancing downforce and drag Track-Inspired Styling – Aggressive contours that give the G90 M5 a sharper, more athletic front-end look Bottom line: if you’re looking to elevate your G90 M5’s front-end styling while adding real aerodynamic benefit, the ADRO Carbon Fiber Front Lip delivers.

Add some carbon to your M-Performance rear valance! Dry carbon fiber's name comes from its manufacturing process.

In celebration of Vorsteiner's 20th anniversary, the company has introduced a modernized version of the V-CSL Carbon Fiber Program for the BMW E46 M3. The new V20 program features dual acorn-shaped snorkels integrated into the front bumper, along with a redesigned one-piece front spoiler. The double-sided carbon fiber hood includes raised vents on both sides to enhance hot air extraction from the engine bay. Additionally, the rear diffuser now incorporates dual diffuser elements, optimizing airflow. Limited to just 103 units, the V20 pays tribute to the remarkable horsepower per liter of the BMW E46 CSL.
