Transform the rear of your Mercedes-AMG GT 63 4-Door Coupe (X290) with the RENtech Carbon Fiber Rear Diffuser-engineered for aggressive styling, improved airflow, and OEM-level fitment Constructed from 100% prepreg carbon fiber, the RENNtech AMG GT 63 Rear Diffuser was designed, engineered, and tested in-house at RENNtech headquarters in Stuart, Florida, then manufactured in Germany.

Explaining the engineering behind our RENNtech fender extractors for the AMG GT C190 because they are not simple replicas of the AMG GT R PRO design. Through extensive analysis and development, we optimized their shape and enlarged each opening to evacuate high-pressure air from the front wheel housings more effectively.
The result: increased front-end downforce, reduced understeer tendencies, and a more aggressive appearance that serves a real aerodynamic purpose.
These benefits are amplified when the extractors work together with the complete RENNtech aero system—including the front canards, side skirts, rear diffuser, and rear wing. Every component was developed to function as one cohesive package, creating a more balanced, stable, and confidence-inspiring driving experience.
