RennTech rear diffuser specifically designed for the CLS 55 AMG is the companion component and perfect addition to our 3-piece carbon front splitter. It visually enhances the rear of the CLS, acts as a functional component of the vehicles exterior in order to decrease drag and increases rear down force. This is accomplished by improving the underbody airflow and allowing for a smooth transition to ambient air when the vehicle is at speed.
RennTech carbon fiber rear diffusers manage the airflow underneath the car, creating low pressure areas that act like a vacuum, pulling the car to the ground for enhanced stability at speed. In addition, the rear diffuser offers an aggressive look and enhancing rear styling. The diffuser is available in both matte and gloss UV protected finishes.
