Model History and Information: RAUH-Welt BEGRIFF (RWB) was founded in Japan in the late 1990s by Akira Nakai, whose first project, a damaged Porsche 911 that he rebuilt, became known as "Stella Artois". The name RAUH-Welt BEGRIFF translates roughly as "Rough World Concept" and refers to Rough World, the drift crew Nakai belonged to before he turned to Porsches. An RWB conversion replaces the front and rear bumpers, side skirts and wheel arches with a riveted wide-body kit and adds a large rear spoiler, and each finished car is given its own name.
