Elevate the rear-end aesthetics and aerodynamic profile of your Honda Civic with the CMST Carbon Fiber Rear Diffuser. Designed specifically for the 10th Gen Civic FC2 models with a dual-exit exhaust configuration, this precision-engineered component replaces the standard rear bumper valance to deliver a dramatically more aggressive and purposeful stance. Crafted by CMST, this diffuser is a premier upgrade that enhances visual appeal while contributing to improved rear-end stability.
Constructed from authentic, high-grade carbon fiber, this rear diffuser combines lightweight performance with exceptional strength. The standard finish features a pristine 3k (2x2) twill weave pattern protected by a high-gloss UV-resistant clear coat, ensuring the vibrant carbon texture remains protected from fading and environmental damage. For a more custom look, optional forged carbon patterns and a matte finish are available, allowing you to tailor the component to your exact aesthetic preferences.
All CMST carbon fiber parts are supplied with AME Motorsport's guarantee of quality, fitment, and customer satisfaction.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
