Carbon rear diffuser

Because you like it sporty

In motorsport, rear diffusers are used to separate the airflow from the underside of the car and accelerate it. This separation of the airflow creates a negative pressure that pulls the car towards the road and thus increases downforce. This in turn increases the stability of the car at high speeds and reduces fuel consumption.

Optical rear diffusers from Carbon Production

However, rear diffusers are not necessarily only good for motorsport to improve the aerodynamic design. We currently mainly produce optical rear diffusers made of carbon, which turn the rear of your car into a real eye-catcher.

What are the benefits of a carbon fiber rear diffuser?

A rear diffuser as elegantly designed as ours noticeably improves the appearance of a car. The lines of the vehicle appear smoother and more aerodynamic. Overall, the car looks sportier – and depending on the rear diffuser, more aggressive or more elegant.
Many drivers opt for an optical carbon rear diffuser because it makes the car look many times faster without actually increasing its performance. Accordingly, an optical rear diffuser is also more cost-effective than a rear diffuser that increases aerodynamic performance.

Elegant design from the finest craftsmanship

Carbon is high-strength, weather-resistant, lightweight AND it looks damn good! Our rear diffusers are handmade from high-quality carbon fiber and are completely “Made in Germany”.
