Customizable Options Include
Custom carbon fiber body panels for lightweight racing vehicles, including nose cones, cockpit covers, side panels, wheel covers, rear covers, hoods and underbody panels. We support custom shapes, split-line design, surface quality requirements and production-ready tooling based on your drawings, samples or vehicle structure.
Choose gloss carbon, matte carbon, colored carbon, forged carbon, custom weave patterns, racing stripes, team logos, sponsor graphics and number decals. Branding can be integrated through decals, clear coating, surface finishing or mold-based logo details.
Custom Logo Branding
Your racing logo can be customized through under-clear-coat decals, CNC mold-engraved logos, metallic badges or surface decals, depending on your branding style and production needs. For premium carbon fiber parts, we recommend applying the logo before the final clear coat, so the branding is sealed under the lacquer layer, protected from scratches, peeling and daily wear. For OEM and private label projects, we can also use positioning jigs and QC check gauges to keep every logo accurately aligned across sample and batch production.
Custom dimensions, mounting points, inserts, brackets, screw holes and chassis interfaces based on CAD files, 3D scans, samples or technical drawings. We support fitment checks and prototype validation before batch production.
3D Scanning Support
For projects without complete CAD files, we can capture accurate vehicle or component data through on-site 3D scanning. The scanned data helps us understand the real surface, mounting area, clearance space and body structure before design or tooling begins. This allows our engineering team to reduce fitment risks, improve surface alignment, and convert real product geometry into usable data for CAD design, mold development, prototype validation and production.

Heavy Chassis Limits Racing Performance
Pain Point:
Traditional metal or standard composite chassis are often too heavy for Le Mans-style endurance racing. Extra weight directly affects acceleration, cornering speed, fuel efficiency, and overall track performance.
Our Solution:
Jcsportline uses a carbon fiber and epoxy composite structure with a modular chassis design to reduce weight while maintaining high rigidity. Compared with traditional metal chassis, it helps reduce chassis weight, improve handling response, and support better racing efficiency.
Slow Customization Delays Racing Projects
Pain Point:
Conventional chassis development usually requires long lead times and high investment. This makes it difficult for racing teams and project developers to respond quickly to custom modifications, aerodynamic updates, or changing race regulations.
Our Solution:
Jcsportline supports custom carbon fiber chassis development with modular structure design and flexible engineering support. Key sections such as side pods, front/rear covers, and wheel arch components can be developed separately, helping clients accelerate design updates, reduce modification costs, and adapt faster to project requirements.
Poor Precision and Weak Reliability Increase Race Risk
Pain Point:
Lightweight chassis often struggle to maintain enough rigidity, fatigue resistance, and impact strength. At the same time, low manufacturing precision can cause large assembly gaps, poor aerodynamic execution, higher drag, and handling loss.
Our Solution:
Jcsportline combines dedicated laminate design, autoclave molding, and 5-axis CNC machining to improve strength, consistency, and fitment accuracy.For finished products, surface profile tolerance is controlled within 0.5 mm, while assembly gap tolerance is typically maintained within 0.3 mm,, helping ensure stable structure, precise assembly, and better aerodynamic performance.
