This RennTech rear diffuser creates an all new aggressive and functional aesthetic for the rear of the 212 E63 AMG wagon. The design and engineering teams at RennTech HQ spent countless hours fine tuning the part to perfectly compliment the E63 AMG 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 beautiful 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.
