This RENNtech rear diffuser creates an all new aggressive and functional aesthetic for the rear of the 212 - E63 wagon. The design and engineering teams at RENNtech HQ spent countless hours fine tuning the part to perfectly compliment the E63 exterior while improving the underbody airflow. There are five separate parts constructed from 100% pre-preg carbon fiber that make up the diffuser assembly; the upper brow, the lower diffuser panel, and three individual diffuser blade elements. This complex part break up opened up the overall design flexibility and allows for much easier serviceability for the end user.

The diffuser assembly also features a unique acrylic coating process which protects the carbon fiber from any harmful UV and humidity degradation. This acrylic coating is applied inside and out to ensure full coverage and protection, unlike any other coating process. Once the acrylic coating is cured, the part is then covered using a high end automotive clear coat to create a gorgeous gloss finish.

RENNtech also developed all new CMC (Ceramic Matrix Composite) exhaust tips specifically for this rear diffuser. This particular material and manufacturing process has been utilized in Formula 1, Le Mans, and various aerospace programs. CMC is known for its superior strength and lightweight qualities, as well as resistance to extreme heat applications. The material is cured at an astounding 2500 degrees Fahrenheit. Therefore, heat from your exhaust will never effect these beautifully tailored blow through exhaust tips. This rear diffuser and exhaust tip assembly is designed to fit the 212 - E63 facelift wagon model from 2014 and up. Modifications to the OEM rear fascia are necessary, installs with a combination of OEM and supplied hardware.

This kit includes:
Carbon fiber diffuser
Carbon fiber tow hook door insert
Cmc exhaust tips
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.
