Product Details

Seibon Carbon Fiber Rear Diffuser

Product Introduction

Aesthetically, the rear diffuser adds aggressive styling to the rear of your BMW, however, a carbon fiber rear diffuser takes that aggressive look and bumps it up, creating a truly unique and eye-catching level of styling to your vehicle.

Features and Benefits Of This Product

The technical function of a rear diffuser involves handling the high velocity airflow from the front of the vehicle as it passes through the underbody. The diffuser eases this high velocity air and also helps fill in the area behind the car, increasing downforce by reducing drag on the vehicle. The diffuser also imparts upward momentum to the air which further increases downforce. Think of an air diffuser on an air conditioning vent. Without it, the air would just blast through the outlet. With the diffuser installed, the airflow is controlled and efficiently distributed.

The exceptional quality of Seibon carbon fiber rear diffusers are the result of over 15 years of experience producing meticulously hand produced carbon fiber parts. Each piece is meticulously hand-crafted using only the finest materials available. Seibon's production processes allow exceptional carbon to resin ratios, creating high product stiffness and as a result, promote exceptional strength.

To ensure the best possible appearance, a great deal of effort is also invested into maintaining a consistent weave pattern from piece to piece. To highlight the weave pattern, Seibon products are protected with a glossy clear coat that resists chipping and flaking and produces a stunning finish.

Prior to leaving the factory, all Seibon products are thoroughly inspected to ensure strict quality control standards and customer satisfaction.

Creating performance-oriented products that contribute to shedding unnecessary weight while amplifying style is Seibon's specialty.
