Exterior Body Kit Development
For exterior styling parts, good appearance is only the starting point. A successful body kit must follow the vehicle’s body lines, install cleanly, protect the mounting structure, and remain repeatable in batch production.

|---|---|
Side Body Parts | Side skirts, fender trims, side extensions |
Rear Body Parts | Rear diffusers, rear bumper vents, rear spoilers |
Large Exterior Parts | Hoods, fenders, roof spoilers |
Full Kit Programs | Complete body kits, widebody kits, private-label kits |
Engineering Checks
Recommended Materials / Processes
Wet Carbon / Vacuum Infusion | Cost-effective exterior styling parts and medium-volume programs |
|---|---|
Dry Carbon / Prepreg | Premium body kits, hoods, racing splitters and lightweight performance projects |

Body Kit Development Process
3D Scanning Data
Original full-vehicle or local 3D scanning; collect mounting points and body-line data. Overseas teams can provide on-site scanning in Europe / the United States.
Concept Sketch
Create 2–3 styling direction sketches based on the customer’s positioning and design style.
Render
Generate installation renderings based on the original vehicle model. These renderings are for visual confirmation only and do not mean tooling has started.
3D Reverse Engineering
Build an accurate base vehicle model by reverse engineering the scan data.
3D Design Modeling
Design front lip, side skirt, rear lip, wing/spoiler and other body kit structures; process mounting points, part-splitting plan and DFM review.
CNC Mold
Plan the mold solution, complete CNC precision machining and surface treatment.
Sample Production
Produce the first sample, complete surface treatment and clear coat, and issue the first-article inspection report.
Testing & Adjustment
Verify fitment, gaps, strength and appearance through real-vehicle trial installation; fine-tune the mold when necessary.
Customer Approval
Submit sample photos, videos and inspection report; lock the mass-production standard after customer approval.
Mass Production
Start batch production according to the locked standard; inspect each piece before shipment.
CFD Aero Parts Development
Aerodynamic parts must do more than look aggressive. A splitter, diffuser, wing or canard should control airflow, improve stability, reduce unwanted turbulence and support the vehicle’s performance goal.
JC AUTOCARBON uses CFD-driven development logic, prototype validation and real-world testing to develop functional carbon fiber aero parts for track-focused and performance applications.
Front Aero | Front splitters, front lips, canards |

Structural Carbon Parts Development
Structural carbon fiber parts require more than a cosmetic carbon surface. They need controlled layup, stable tooling, accurate interfaces, embedded mounting structures, heat or pressure resistance and reliable assembly.
JC AUTOCARBON supports CAD-driven and sample-driven structural composite projects including intake systems, interior structures, brackets, embedded parts and performance components.

Tooling and sample preparation for structural carbon fiber parts
Four Stages
What we do — from concept to production
You bring the idea. We help shape it into something that can actually be built — checking styling, fitment, composite behavior, mold logic and production consistency before expensive tooling decisions are made.
Concept & Design
You bring the sketch, CAD file, sample part or reference photos. We define styling direction, vehicle fitment, mounting strategy and production feasibility.
Engineering & DFM
Carbon fiber does not behave like metal. We plan layup direction, resin system, reinforcement, parting lines and demolding logic before tooling starts.
Tooling & Prototype
Molds and first samples are built for real fitment checks, surface review, installation testing and structural validation.
Production & Scale
Approved parts move into batch production with controlled QC for surface finish, dimensional accuracy, installation fitment and batch consistency.
Risk Control
Why carbon fiber development projects go wrong
Good renders are not enough. Carbon fiber development fails when design decisions are separated from tooling, installation, material behavior and repeatable production.
Good Looks, Bad Fitment
A render can look perfect, but if surface data is inaccurate or mounting points are weak, the part will not install cleanly.
Design Without Tooling Logic
If mold structure, parting lines and demolding direction are not planned early, production becomes expensive, unstable and hard to repeat.
Prototype Works, Mass Production Fails
Handmade samples can look great. The real question is whether the same part can be produced 100 times with the same surface, fitment and structure.
No Validation Before Delivery
Without fitment checks, dimensional control, UV testing and temperature cycling, problems appear after customers already receive the part.
How we solve it
JC AUTOCARBON solves these problems by connecting design, composite engineering, tooling, prototype validation and production under one development workflow.
Manufacturing Capabilities
Material, process and QC options for different project goals
Different carbon fiber parts need different material systems, tooling choices and production methods. We match the process to the target cost, volume, weight, finish and strength requirements.
Dry Carbon
Prepreg, autoclave or oven-cured parts with high strength, lower weight and premium surface quality.
Best for premium and performance-focused parts
Wet Carbon / Vacuum Infusion
Cost-effective exterior parts, large panels and medium-volume programs where visual carbon finish and production efficiency matter.
Best for styling parts and balanced cost
Compression Molding
Repeatable batch production, forged carbon parts and complex molded structures where cycle time and consistency are priorities.
Best for repeatable batch production
Weave & Finish Options
2×2 twill, plain weave, 12K large weave, forged carbon, colored carbon hybrid patterns, gloss, matte and custom logo weave support.
Best for brand differentiation
Structure & Installation
One-piece or split construction, embedded metal inserts, OEM replacement mounting, add-on tape/clips/bolts and bracket-mounted solutions.
Best for real-world installation
QC Systems
Surface inspection, dimensional control, vehicle fitment checks, installation validation, UV testing, temperature cycling and batch consistency records.
Best for lower after-sales risk

Why JC AUTOCARBON
Why brands choose JC AUTOCARBON for custom carbon fiber development
A custom carbon fiber project is not only about making a good-looking part. It requires accurate vehicle data, composite engineering, tooling logic, fitment validation and stable batch production. JC AUTOCARBON connects these steps under one development workflow, so brands can reduce tooling mistakes, launch faster and scale with confidence.
In-House Development Workflow
Design, reverse engineering, DFM review, tooling, prototype validation and production are coordinated in one system instead of being separated across disconnected suppliers.
Composite Engineering First
We plan layup direction, resin system, reinforcement zones, embedded structures and curing methods according to the part’s function, not by guesswork.
Fitment Before Mass Production
Samples are checked on real vehicles or assemblies for gaps, mounting points, installation logic and structural performance before batch production begins.
Production-Ready Thinking
Every design is reviewed against mold structure, demolding direction, surface quality, repeatability, QC standards and future volume needs.
