What is an RWB Porsche

RWB or RAUH-Welt Begriff is a Japaneses car tuning company, founded by Akira Nakai-San in the 90’s. RAUH-Welt Begriff translated means “Rough World Concept”. Most famous for their signature wide-body air-cooled Porsche’s and the manner in which Akira Nakai installs each kit personally on site.

Each RWB car is unique and receives a name from Akira and no two cars will ever be the same. The car is setup based on needs and requirements but also the personality of the owner which is derived from the personal installation process. Each customer is only entitled to one RWB build. The price of an RWB kit varies on what each install requires.

Who is Akira Nakai

Akira Nakai is a Japanese car tuner and the founder of Porsche tuning company RAUH-Welt BEGRIFF (RWB), which specializes in the design and installation of custom wide-body kits on older Porsche models.

Akira Nakai’s career got started with a drift crew called Rough World, from there he started to work on Porsches while employed by a body shop when he came across a damaged one and got his hands on it in the late 90s.

Nakai later started his own company called RAUH-Welt Begriff (RWB)

Building an RWB Porsche

Due to the personal installation and the world-wide attention gained in recent years, the RWB waiting list is said to be about 2 years, with parts needing to be fabricated to suit your car and payment for the RWB kit required in full on application.

A typical RWB kit usually includes a new front bumper, rear bumper, side skirts, wheel arches, spoilers and suspension setup.

Each RAUH-Welt Begriff kit is ceremonially finished with the RAUH-Welt windshield banner being applied.
