Seibon carbon fiber aerodynamic and body upgrades are hands down some of the best quality parts available. Starting off in 2004, Seibon has become one of the most recognized names in carbon fiber accoutrements. Every component is constructed with a consistent weave pattern and uses one single carbon fiber sheet which ensures no breaks in the lines. Seibon's processes allow excellent carbon/resin ratio, creating high product stiffness that also leads to extra strength. Seibon's products are coated with a UV protected glossy clear coat that does not chip or flake, and also feature a rolled edge for premium look and fitment.

Creating performance-oriented products that help shed unnecessary weight without sacrificing style is Seibon's specialty. Contributing to its higher end luxury line up of hoods, spoilers, trunks, etc., is this carbon fiber rear diffuser. The purpose of a rear diffuser is to reduce air turbulence as your car drives at high speeds. Rear diffusers decrease drag, making your car more stable at high speeds and reduce the amount of wind resistance it must overcome. Less wind resistance means your vehicle will be able to utilize its existing horsepower and torque more efficiently. This Seibon rear diffuser is also the perfect answer to enhance and maintain that superior look of carbon fiber to your car.
