About Us

Driven by Automotive Passion

What started as a personal mission to fix broken, obsolete parts on a classic Audi TT Mk1 quickly evolved into J81.UK. We realized that many enthusiasts were struggling with the same fragile interior plastics and unavailable exterior trims.

Today, we utilize state-of-the-art 3D scanning and industrial-grade additive manufacturing to not just replicate, but improve upon original OEM designs. While our roots are in the 8N chassis, we are actively expanding our catalog to design and manufacture custom solutions for a wider range of classic and modern vehicles.
