About
The RWB Worldwide Registry documents every Porsche built by Akira Nakai of RAUH-Welt Begriff.
Our Mission
To be the place to find everything about RWB cars: where each one lives, how it was built, and the story behind it. The registry is run by enthusiasts and grows with every contribution.
Who is Akira Nakai?
Akira Nakai is the founder of RAUH-Welt Begriff. He came from Japan’s drift scene, moved from the AE86 to the Porsche 911 in the late 1990s, and has built almost every RWB car himself ever since.

What is RWB?
RAUH-Welt Begriff stands for “Rough World Concept”. RWB cars are wide-body Porsches with a raw, race-inspired look. Each one is built for its owner, so no two are the same.
