Custom Carbon Fiber Parts Package
BMW M3 Aerodynamic kits
Engineered. Customized. Delivered.
An aero kit usually includes a front splitter, canards, side skirt extensions, rear diffuser, rear wing, and spoiler — built to control airflow and keep the car stable at speed.
The What's Included section below shows the parts we have listed. Not shown does not mean not made — some projects are protected by NDA. Send us the parts you want, and we will quote and produce the kit for you.
At JC AUTOCARBON, every aero part is designed for real airflow, not just looks — dry carbon fiber, light and strong, tested for fit before it leaves our factory.
What’s Included
Please note: This table lists the parts we most often make for this package — not the full range. We have produced many more parts for this model, and we can build new ones for you. If you don’t see a part here, send us a photo or drawing and we will check it for you.
Minimum order: 20 pieces in total, mixed freely. Any mix of parts from that adds up to 20 pieces.

Our Development Process
Different carbon fiber projects need different development logic. Choose the path that best matches your project type — exterior styling, aerodynamic performance, or structural composite parts.
Overall timing note:
After design data is confirmed, most projects can complete first samples in 45–58 days. CNC mold making usually takes 15–20 days, mold replication 20–25 days, and sample production 15–20 days. Early design and confirmation time are not included.
Exterior Body Kit Development
Best for front lips, side skirts, diffusers, spoilers, hoods, fenders and complete body kits.
CFD Aero Parts Development
Best for splitters, rear wings, diffusers, canards, hood vents and track-focused aero kits.
Structural Carbon Parts Development
Best for intake systems, interior structures, brackets, embedded mounting parts and CAD-driven components.
