When it comes to designing and producing carbon fiber car parts, precise fitment isn’t just about aesthetics — it directly affects user experience and driving safety. Yet, many customers face recurring pain points during installation:
Excessive gaps that compromise the overall appearance and may cause safety risks
Improper clip thickness leading to loose installation
Bumper modifications required on some models, increasing labor and cost
Complicated installation processes that take hours and add labor expense
A well-known European tuning shop, Lucas, faced recurring issues while installing a carbon fiber side skirt for a popular model. The first sample had poorly designed clips and visible edge gaps, resulting in negative customer feedback.
By collaborating with JCSPORTLINE, they implemented vehicle-based testing and dimensional data comparison — leading to a perfectly fitting product.
We use three levels of sample testing to ensure that our parts fit right — every time.
We locate the target model and conduct direct on-car testing. This allows us to adjust clips and edges in real time, ensuring compatibility with OEM structures.
For models not available domestically, we partner with international clients by shipping samples to them. Their installation feedback is used to make product improvements.
We cross-reference vehicle scan data, mold scan data, and part scan data. This triple-layer check helps us optimize the mold for accurate fitment.
Thanks to our rigorous testing, we’ve helped clients:
At JCSPORTLINE, we believe that product quality and installation experience must go hand-in-hand. Only through strict testing and technical refinement can we deliver carbon fiber parts that truly stand out — not only in performance, but also in ease of use.
If you're struggling with carbon fiber part installation — or simply want to improve the fitment, efficiency, and user experience — we’re here to help.
Let’s work together to make your carbon fiber upgrades easier, better, and more professional.
