About

Welcome to the RWB Worldwide Car Registry, a comprehensive and community-driven project dedicated to documenting every Porsche meticulously crafted by the legendary Akira Nakai of RAUH-Welt Begriff (RWB).

Our Mission

Our mission is to celebrate and preserve the legacy of Akira Nakai’s unparalleled craftsmanship by creating the most complete and accurate registry of RWB cars worldwide. Each car is a testament to Nakai-san’s unique vision and the fusion of Japanese tuning culture with German engineering.

Who is Akira Nakai?

Akira Nakai Japanese car tuner and the founder of RAUH-Welt Begriff (RWB), a tuning company that specializes in modifying Porsche cars. Renowned for his distinctive wide-body Porsche creations. Nakai-san’s journey with RWB began in the 1990s, starting with a personal passion for modifying his own Porsche 930. His unique approach combines Japanese car culture with the engineering and aesthetics of German cars. Since then, Nakai-san has built a global following with his aggressive and highly personalized designs. His hands-on approach means that each RWB Porsche is not just modified, but transformed into a work of art that reflects his dedication to perfection and individuality.

What is RWB?

RAUH-Welt Begriff (RWB) translates to “Rough World Concept” and epitomizes a bold, race-inspired aesthetic. Combining over-the-top styling with functional performance upgrades, RWB Porsches are instantly recognizable. Each build is custom-tailored by Nakai himself, ensuring no two cars are identical and each tells its own story.
