Seibon 16-17 Honda Civic Sedan GT Carbon Fiber Rear Spoiler

Seibon Carbon Fiber Rear Spoilers are more than just an aesthetic upgrade — they’re a critical aerodynamic enhancement for the serious enthusiast who understands the importance of rear-end stability at speed. Whether you're tracking the car or simply looking to make a statement at a local meet, Seibon's spoilers combine aggressive styling with motorsport-derived function.

Crafted from high-grade carbon fiber and formed using advanced vacuum infusion techniques, each spoiler is engineered to offer both lightweight strength and precision fitment. The result is a wing or lip that not only looks stunning with its deep gloss finish and tight weave pattern, but also resists heat, UV damage, and flex under pressure.

Aerodynamically, a properly designed rear spoiler helps to generate downforce and reduce lift at high speeds by manipulating the airflow coming off the roofline and trunk. This improved airflow management contributes to increased rear tire traction and vehicle stability during cornering, acceleration, and braking.

Seibon offers a range of rear spoiler styles — from subtle duckbill lips to aggressive GT-style wings — to match your vehicle’s form and function goals. Most units are designed as direct bolt-ons or require minimal modification, making them a seamless addition to your aero setup. Pair your spoiler with Seibon’s hoods, side skirts, and diffusers for a unified carbon fiber presence that turns heads and performs under pressure.
