Our rear diffuser specifically designed for the CLS63 Biturbo 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.
As with the front splitter, our proprietary rear diffuser was designed and engineered in-house; is manufactured using the same high quality prepreg carbon fiber and is a quick and easy install that requires no modifications to the CLS’s rear bumper.
The center section of the diffuser also accepts the EU third brake light or may also be removed and a mesh grill insert installed for an even more customized look. The rear diffuser also fits with the OEM exhaust tips
