Inside Our Carbon Fiber Factory
Every part is born here:
1. Pre-preg carbon laid by hand in steel molds
2. Autoclave cured at 150°C, 6 bar pressure
3. CNC trimmed to ±0.1mm tolerance
4. Quality checked with 3D laser scanners
Behind every TOPSTH part is a team of 50+ craftsmen working in our 50,00 sq ft factory. From cutting pre-preg carbon to final QC under LED lights — every step is done in-house.

10 years of manufacturing race-proven carbon fiber for Tesla, BMW & Audi owners.
