Build Your Own Carbon Fiber Aero Kit - F8X M3/M4

Build Your Own F8X Carbon Fiber Aero Kit

Create a fully custom exterior transformation for your F80 M3, F82 M4, or F83 M4. This kit lets you mix and match any carbon fiber piece from our entire F8X lineup to build the exact look you're after, whether that's subtle OEM+ refinement or full-on track-ready aggression.

Every component is constructed from high-quality carbon fiber and finished with a UV-protectant gloss coat for lasting durability and rich visual depth. All pieces are backed by our fitment guarantee.

Choose Your Front Lip

Why Build Your Kit?

Select any combination from our complete F8X carbon fiber lineup to create a kit that's entirely yours. No forced packages or pre-selected bundles. Bundling your pieces together also saves you money compared to purchasing each part individually.

Shipping & Handling

Please allow 3–5 business days for your order to process and confirm inventory. Each piece in your kit is carefully inspected and packaged individually to ensure everything arrives in perfect condition, and boxes will ship separately. If any items are backordered, you'll receive an email with alternative options.
