RWB/RAUH-Welt BEGRIFF is a Porsche tuner located in Japan and has now opened its US Operations in California. RWB has combined Japanese and Euro tuning elements, creating the distinct RWB style for Porsche chassis. Starting off as a small countryside body-shop in Chiba-Ken, RAUH-Welt 911’s are now a common sight on both the streets and racing circuits of Japan. We create only one RWB Porsche for each customer.

All RAUH-Welt Bodykits are made in Japan and are built very sturdy by hand. Each RWB Car is built by Nakai-san & each customer is given the utmost gratification when Nakai-san has completed their build.
