Extreme Porsche performance and bespoke engineering.

9FF Engineering is a globally recognized German performance specialist dedicated to pushing the limits of the Porsche 911.

With a relentless focus on engineering precision and individuality, 9FF develops high-performance upgrades and complete vehicle conversions that transform standard Porsche models into extreme, tailor-made machines. From powertrain modifications to full bespoke builds, every project is approached with uncompromising attention to detail.

Established through years of technical development and innovation, 9FF is TÜV-certified and officially registered as a vehicle manufacturer with the German Federal Motor Transport Authority — placing them among a select group of companies capable of delivering fully engineered, road-legal performance cars.

Rather than building a single definition of the “perfect car”, 9FF builds each car around the individual. Every project reflects the vision of the owner — refined through engineering expertise and executed to the highest standards.

Where others stop, 9FF continues.
